Changes in Waves

In a longitudinal wave the particles move...

• in the same direction as the wave travels.

• perpendicular to the direction the wave travels.

In a transverse wave the particles move...

• in the same direction as the wave travels.

• perpendicular to the direction the wave travels.

As the period of a wave increases, what happens to the wave's length (wavelength)?

• the wavelength increases

• the wavelength decreases

As the period of a wave increases, what happens to the wave's frequency (I said it, frequency)?

• the frequency increases because the waves become more frequent.

• the frequency decreases because the waves become less frequent.

As the frequency of a wave increases, what happens to the wave's length (wavelength)?

• As frequency increases the wavelength decreases.

• As frequency increases the wavelength increases.

Frequency is...

• how many times a wave oscillates per second.

• the time is takes for one wave to pass.

• the length of a wave.

• the height of a wave.
