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.

2: The waves get larger,
3: They get smaller.
4: The waves get faster as frequency increases
5: The waves decrease in speed as the frequency decreases.
6: The energy moves through the green dots.

1.When you increase the amplitude, the waves get bigger.
2. When you decrease the amplitude, the waves get smaller.
3. When you increase the frequency, the waves move faster and begin to get tighter and tighter together, 'til there isn't any space left.
4. When you decrease the frequency, the waves stay together and do not come apart.

The waves increase speed when you increase the amplitude.
The waves slow down when you decrease the amplitude.
The waves increase speed when you increase the frequency.
The waves slow down when you decrease the frequency.
The dots move up and down but stay in place because the energy waves go through things but don't move things.

when increased the amplitude the waves got bigger.
but when i decreased it the waves got smaller.when i increased the frequency the waves where made at a faster rate but when i decreased it the were made very slow. this happens bececuase energy dissipates and the wave start out strong but become smaller as the energy disperses.

The height in which the wave is coming from is increased when you increase the amplitude. The height in the wave is shortened when you decrease the amplitude. The pace in which the wave vibrates is dramatically increased when in increase frequency. The vibration is decreased a lot when you decrease the frequency. The dots on the waves are just going up-and-down; they are not moving around.

2.the waves get bigger
3.the waves are smaller
4.the waves go very fast
5.the waves stop
6. i think this happens because the energy is traveling threw the dots

1. when you increase the Amplitude the chain moves faster.

2.when you decrease the amplitude the chain moves slower until it stops.

3.when you increase the frequency the chain on one end go really fast then on the other end it starts to go slow.


4.when you decrease the frequency the chain start to become wavy then it stops.

5.the reason why the dots stay in the same spot while moving because energy flows through the dots and not the other way around.

2. The waves get bigger when you increase the amplitude.

3. The waves get smaller when your decrease the amplitude.

4.The waves get a little smaller and the waves get much faster when you increase the frequency.

5. The waves get slower when you decrease the frequency.

6.Energy is flowing through the dots.

When you increase the amplitude the waves get bigger.When you decrease the amplitude the waves get smaller.When you increase the frequency the waves get faster.When you decrease the frequency the waves get slower.The dots stay in place because energy moves threw material not energy its self.

# What happens to the waves when you increase amplitude?
the waves get bigere.

# What happens to the waves when you decrease amplitude?
no waves and the get smaller.

# What happens to the waves when you increase frequency?
it go faster and it is bigger waves.

# What happens to the waves when you decrease frequency?
it is calm and nothing happens.

When you increase it never end and the waves increases.when you increases the speed.it stays the same. it goes slower.it pushes the waves

2 . When you increase the amplitude , it makes the waves go faster and bounce a lot more .

3 . When you decrease the amplitude , the waves don't move as fast and they don't move as high .

4 . When you increase frequency , the waves move very fast .

5 . When you decrease the frequency the waves barley move or stop .

6 . The waves stay somewhat in the same place , because they are in a line and the wave is not moving it stays in one place when its shaken .

1.
When you increase amplitude the wave get bigger and faster.

2.
when you decrease amplitude there are no wave at all.

3.
when you increase frequency the waves move very fast but at the end slow.

4.
when you decrease frequency it goes very slow and barely moves.

5.
the dots stay in place while going up and down is because the wave frequency is so close because the energy is holding it together.

When the amplitude is increased the waves become larger and when it is decreased the waves become smaller. When you increase frequency the waves go faster and when decreased the waves go slower. The balls stay in place because of the wave length and the trough.

Because, the Frequency and the Amplitude is low and because of the wavelenth.

When amplitude is increased, the starting point starts to go higher.

When amplitude is decreased, the starting point starts to go lower or it stops.

When frequency is increased, the starting point starts to go faster.

When frequency is decreased, the starting point starts to go slower.

The reason the dots on the line stay in the same place because until the amplitude, frequency, and/or wavelength are disturbed, the dots position is unchanged.

1. When the wave increase's the waves move higher.

2. They don't move as high when you decrease the amplitude.

3. When you increase the frequency the waves move faster.

4. When you decrease the frequency it moves slower.

5. They stay in place some what when you move them because they are all in line and connected.

When you increase amplitude the waves become stronger and higher.

what happens to the waves when decrease amplitude is there are no wave at all.

6. They stay in place some what when you move them because they are all in line and connected

what happens to the waves when you increase frequency is that they bonce really fast.

what happens to the waves when you decrease frequency is the waves stop.

When you increase the amplitude the wave increases in size, When you decrease the amplitude the wave decreases in size, When you increase the frequency the wave speed increases, When you decrease the frequency the speed of the wave goes down, When the dots go up and down they stay in the same place because idk

when you increase amplitude the waves increase. when you decrease amplitude the wave decrease. when you increase frequency the wave move faster. when you decrease the frequency the wave become slower. when the dots are going up and down while staying somewhat in place this happens because i don't know

When you raise the amplitude the wave will increase. But if you don't it will stay the same length and if it is too high it will go down gradually. When you add frequency this wave will go faster. If you decrease the frequency then you will see that it is going slower. Waves go up and down because it is energy that move through something or between something in some kind of energy. Like light energy that moves in between sound waves.
