Question

Which of the following statements about frequency is correct?


Frequency is the distance between two consecutive crests of a wave


Frequency is the number of waves that pass a point in one second


Frequency is the speed at which a wave travels through a medium


Frequency is the height of the wave from its rest position

Answer 1

Correct answer: "Frequency is the number of waves that pass a point in one second."

Explanation:
- Frequency (f) = number of cycles per second, measured in hertz (Hz).
- Distance between consecutive crests = wavelength (λ).
- Speed at which a wave travels = wave speed (v), related by v = f·λ.
- Height from rest position = amplitude.
