ANSWER
A. 100 Hz
EXPLANATION
Given:
• The velocity of the wave, v = 300 m/s
,• The wavelength, λ = 3 m
Find:
• The wave's frequency, f
The frequency of a wave with a wavelength λ and a velocity v is,
[tex]f=\frac{v}{\lambda}[/tex]Replace the known values and solve,
[tex]f=\frac{300m/s}{3m}=100Hz[/tex]Hence, the frequency of the wave is 100 Hz.
