Answer:
Frequency = 8 Hz ; Period = 0.125 s
Step-by-step explanation:
The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.
The Displacement marked A in th picture is tbe Amplitude of the wave
The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).
2.)
Given that :
Velocity (V) of wave = 20 m/s
Wavelength (λ) = 2.5 m
The frequency (f) of the wave ;
f = v /λ
f = (20 m/s) ÷ 2.5m
f = 8 Hz
The period T of the wave :
T = 1 /f
T = 1 / 8
T = 0.125 seconds
