Answer 1

Question:-

The speed of a wave is 40 m/s. If the wavelength is 80 centimeters, what is the frequency of the wave ?

Answer:-

Given:-

Velocity (V) = 40 m/s

Wavelength $(\lambda)$ = 80 cm = 0.8 m

To Find:-

The frequency (F) of the wave.

Solution:-

We know,

$\bf V \: = \: F \: × \: \lambda$

40 = F × 0.8

F = $\frac{40}{0.8}$

F = 50

The frequency of the wave is 50 Hz. [Answer]
