The distance between two successive crests of a wave is 15cm and the velocity 300ms-1. Calculate the frequency.
A
2.0x102Hz
B
4.5x103Hz
C
2.0x103Hz
D
4.5x102Hz
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Wavelength = 15cm = 0.15m
Velocity = 300m/s
V = fx
F = V/Wavelength
F = 300/0.15 Hertz
F = 2 x 103Hz
