A vibrating tuning fork emits sound waves of period `2 xx 10^(-3)` second and wavelength 0.7 m in air. The velocity of sound in air is

A

175 m/s

B

330 m/s

C

340 m/s

D

350 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
`v = (lamda)/(T) = (0.7)/(2 xx 10^(-3))`
`= (700)/(2) = 350 m//s`
