Which statement correctly compares waves A and B?

• Wave B has a greater amplitude than wave A.

• Wave A has a greater amplitude than wave B.

• Wave B has a greater frequency than wave A.

• Wave A has a greater frequency than wave B.

Answer explanation

The crest of B is higher than A, so B has a greater amplitude. Their frequencies are the same because they both have 3 crests.

Which is measured by the distance between two troughs of the wave?

• Amplitude

• Frequency

• Speed

• Wavelength

Answer explanation

Troughs are two points that are the same. The distance between them is the wavelength.

What property of the wave is the student changing?

• Amplitude

• Frequency

• Speed

• Wavelength

Answer explanation

The height of the waves are changing so they are changing the amplitude.

If the force that produces the wave is increased in strength, what must be true?

• W will increase.

• X will increase.

• Y will decrease.

• Z will decrease.

Answer explanation

More force would increase the amplitude. Therefore, W would increase.

(While Y could also show the amplitude, the answer says Y would DECREASE. That is wrong)
