A wave is a moving disturbance that transfers energy through matter or space.
Investigate the wave simulator below....

....answer the following questions in the blog section...
  1. Set the wave simulator to "oscillate" and "no end"
  2. What happens to the waves when you increase amplitude?
  3. What happens to the waves when you decrease amplitude?
  4. What happens to the waves when you increase frequency?
  5. What happens to the waves when you decrease frequency?
  6. Notice that the dots on the wave go up and down while staying somewhat in place...explain why this happens...make sure you use what you know about energy waves to answer.

When I increase amplitude the waves increase speed and move a lot faster.
When i decrease amplitude the waves move more slowly.

When I increase frequency the length of the wave gets longer and faster.

When I decrease frequency the length of the wave became shorter and slower .


The dots stay somewhat in place because the gravitational energy is pulling them down, which makes the bounce right back in place.Also they stay somewhat in place because say that i am standing still and talking the sound wave will not move unless there is any physical energy or kenetic energy going on.

When you increase amiplitude it gets higher. But when you decrease it , it gets smaller and doesnt make as much waves. An when you increase frequency it gets really fast and theres bigger waves. But when you decrease it, the waves go slower but are really big. And it stays in the same place because its all conected together.

The waves get alot bigger when you increase the amplitude.As you decrease it the waves get smaller.When I increase the frequency the waves got faster each time.When i decreasse it the waves got slower.Cause the high pionts move with the waves.

When I increase the amplitude the waves get faster at the beginning of the wave but at the end of the wave it gets slower.

When I decrease the amplitude the waves stop.

When I increase the frequency,the waves get really fast at the beginning of the wave but at the end of the wave it gets slower.

When I decrease the frequency the waves stop.

The reason the green dots go up and down and stay somewhat in place is because the high points move with the waves.

The waves in the amplitude gets larger as you start to add more to it. As I decrease the amplitude it at a stay still.As I increase the frequency it starts to get larger in its size. The frequency waves are now at a stand still. The dots are staying in place because there was no amplitude or no frequency to make it move.

2. The wave on the string increases in speed and height.

3. The wave on the string decreases in speed and the height.

4. The wave on the string increases in speed but it does not increase in height.

5. The wave on the string decreases in speed and height.

6. The dots on the wave stay in place because the amplitude increases and the frequency decreases in speed.

When you increase amplitude it causes the waves to increase in height and speed.
When you decrease amplitude the waves become shorter and slower.
When you increase frequency the stick goes faster.
When you decrease frequency the stick becomes slower.
Its caused by the crest the crest will only go up and down never to either side cause its the frequency so show how loud something is.

When you increase the wave to amplitude it get higher.
When you decrease the wave it stops and its straight.
When you increase the wave to frequency it gets faster.
When you decrease the wave by frequency it goes down and slow .
Because they all connected together

1.The wave starts to pick it pace, and the wave grows as it gains speed.
2.As we decrease the amplitude, the wave starts to stop moving.
3.The wave starts to pick up speed, until it is pretty much a blur.
4.The wave will slow down, this is a result of decreasing the frequency.
5.cause the dots pose as the wave points, so they stay in place for that reason.

it gets faster. it gets slower. it goes all over. it stops. the waves go up and down because the sound travels through the air

When I increase amplitude,the wave gets stronger.When I decrease amplitude,the wave gets weaker.When I increase frequency,the wave goes faster.When I decrease frequency,the wave goes slower.The dots on a wave stay in place because the energy doesn't last long,so the wave stops.

When you increase the amplitude the waves get larger. When you decrease the amplitude the waves get smaller. When you increase the frequency the waves go faster and the wave length get shorter. When you decrease the frequency the waves slow down and the wave length increases. The dots stay in the same place because energy travels through the wave.

1. As you increase the amplitude, the waves increase over the mid wave line

2. when you decrease the amplitude the waves grow closer to the mid wave live

3. when you increase frequency the wave length decreases

4. when you decrease the frequency the wave length grows

5. the reason the green dots go up and down is because energy doesn't entirely give another object motion, but it but energy can still flow through it

2. as the amplitude increases the waves start to speed up and the waves start getting taller.
3.as the amplitude decreases the waves slow down and start to straighten out.
4. as i increase the frequency the waves start to speed up drastically
5.as the frequency decreases the waves slow down and straightens out
6.the energy transfers through matter

When You Increase The Amplitude The Wave Moves Faster.
When You Decrease The Amplitude The Wave Gets Smaller And Slower. When You Increase The Frequency The Wave Is Shorter But Moves Faster. When You Decrease The Frequency The Wave Gets Shorter And Slower. The Wave Stays In Place While It's Moving Because A Wave Can Move Through Anything Without Disturbance .

When the amplitude is increased the upwerds and downwerds goes quicker,and when its decreased they go slower,when the frequency is increased the beeds go faster then useul,when its decreased the beeds go slower then useul.

when you increase the amplitude it gets higher and faster but when you lower it gets shorter and slower.when you increase the frequency it get longer and when you decreases it gets longer and longer.this happends because the wave gose under the thing

The wave goes the highest when you make it oscillate.As you increase the frequency it goes really high.But when you decrease everything it goes really low because of how much energy is forcing it to go.Theires a manual,wich is the wrench and the wrench you have to wiggle it to move. the oscillate thing it goes by it's self and had a great amount of energy.And the pulse all i't does is Scatter the balls,It don't really make a wave.Only if you increase the amount of everything especially the amount of frequency.

O2. What happens to the waves when you increase amplitude?
It Get Faster And Faster .
O4. What happens to the waves when you decrease amplitude?
It Get Slower And Slower .
O4. What happens to the waves when you increase frequency?
It's High At The Top And At The Bottom And Look Like It Decreased .
O5. What happens to the waves when you decrease frequency?
It Get Very Slow .
O6. Notice that the dots on the wave go up and down while staying somewhat in place...explain why this happens...make sure you use what you know about energy waves to answer.
Because The Waves Go Under The Dots .

When i increase Amplitude the wave goes higher.When i decrease Amplitude the waves go lower.When i increase Frequency , the wave goes much faster but stays the same height for the Amplitude.And when i decrease Frequency the waves go slower and they decrease.And the reason why the dots stay on place are because they are connected together and they are held in place by what's holding them at the end.

• When you increase the amplitude the waves go higher and when you decrease the amplitude the waves get lower.
•When you increase frequency the waves get faster and when you decrease the frequency the waves get slower
•The reason the dots on the wave go up and down while somewhat staying in place is because the waves vibrate , causing them to do the up and down motion while still keeping the dots together.

The waves get bigger at the beginning, but they get smaller at the end. The waves are smaller at the beginning, but then they flatten out at the end. The waves move much faster and are a little bigger. There is hardly any waves when you decrease the frequency. The dots on the wave stay sort of the same because they are all following the same pattern and the tension is high, making it not so loose.
