Question

Choose the correct option and explain:

A note of 500 Hz travels through a solid. If the velocity of sound in the solid is 3500m/s, the wavelength is

(A) 21m
(B) 2m
(C) 3.5m
(D) 7m​

Answer 1

Answer:

(D) 7m

Explanation:

velocity = frequency × wavelength

3500= 500 × wavelength

wavelength = 7m

Answer 2

$\huge{\bold{\star{\fcolorbox{black}{red}{Answer}}}}$

(D) 7m

Given,

Velocity of wave = Frequency × Wavelength

Wavelength = $\frac{Velocity}{Frequency}$

= $\frac{3500}{500}$

= $7m$
