What happens with the number of waves?

1

What happens to the distance between waves (wavelength)?

1

Increase the amplitude. What happens to the number of waves?

1

Decrease the frequency. What happens with the number of waves?

1

What happens to the distance between waves (wavelength)

1

Decrease the amplitude. What happens with the waves?

1

You can have your sound on- but don't have it extremely loud. Push the green button for sound. What do you notice about the waves?

1

What do you notice about the speaker?

1

Now increase the frequency. How does the speaker movement change?

1

What happens to the pitch of the sound?

1

Decrease the amplitude. What happens to the volume?

1

Describe how particles move wave energy.

1

What color is the light?

1

Slide the frequency to the left (to a lower frequency). What happens to the color?

1

What happens to the number of waves (when frequency is decreased)?

1

What happens to the distance between the waves (wavelength) when the frequency is decreased?

1

Slide the frequency to the right (to a higher frequency). What happens to the color?
