If the velocity of a wave is 12 m/s and its frequency is 600 hertz, what would be its wavelength?

Black_prince [1.1K]

Answer:

» λ = 0.02m

Explanation:

Given :

Velocity of the wave {v}= 12 m/s

Frequency {f} = 600 Hz

Apply Wavelength formula :

• $λ = \frac{v}{f}$

→ λ = $\frac{12}{600}$

→ λ = $\frac{1}{50}$

→ λ = 0.02m
