Question

If I time the movement of waves for 1 second, and calculate that 100 waves passed through in that 1 second, what have I calculated?

A.crest
B.amplitude
C.wavelength.
D.frequency.
E.none of the above

Answer 1

Answer:

D.frequency.

Explanation:

The number of times a wave passes through a particular point in a time of 1 second is called the frequency.

Amplitude is the maximum height the wave reaches from the reference axis of the wave

Wavelength is the distance between the two upper (crest) or lower (troughs) points of a wave.

Crest is the top most part of a wave.

Hence, the question is referring to frequency.
