Question

Which statement best describes wavelength?

1. Which statement best describes wavelength? (Points : 1)

Wavelength is the length of two complete wave cycles.

Wavelength is the length of one complete wave cycle.

Wavelength is the speed at which a wave travels.

Wavelength is the same as pitch.

2. As demonstrated by the Doppler effect, why does sound increase in pitch as a sound source approaches you? (Points : 1)

Objects vibrate faster when they move forward.

Objects vibrate slower when they move forward.

The waves are farther apart because the object is moving toward you.

The waves are closer together because the object is moving toward you.

3. Which statement best describes frequency and pitch? (Points : 1)

Frequency and pitch are the same as wavelength and velocity.

Frequency and pitch are the opposite of wavelength and velocity.

Frequency and pitch are never found in a description of the Doppler effect.

Pitch is how frequency is perceived.

Answer

You should do your own homework and not ask people to help you cheat. People who answer obvious test questions or homework questions are not trying to help you. Apparently it just makes them seem "smart" while it keeps you from developing good study skills. Do yourself a favor and do the work yourself.
