The S.I units of frequency, period and amplitude of a wave are respectively

Assessment: WAEC SSCE - Physics - 2006 (Objective) Subject: Physics

Question 1 Report

The S.I units of frequency, period and amplitude of a wave are respectively
Answer Details
The S.I. unit of frequency is hertz (Hz), which is defined as the number of waves that pass through a point per second. The unit of period is second (s), which is the time taken for one complete wave to pass a point. The amplitude of a wave is the maximum displacement of the wave from its undisturbed position, and it is measured in metres (m). Therefore, the correct answer is option (D): hertz for frequency, second for period, and metre for amplitude.
