A source of longitudinal waves vibrates ...

A source of longitudinal waves vibrates 320 times in two seconds. If the velocity of this wave in the air is `240 m s^(-1)` , find the wavelength of the wave .

A

1 m

B

1.5 m

C

2 m

D

2.5 m

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity of wave , v = `240 m s^(-1)`
Frequency of the wave , n = `(320)/(2) = 160` hertz
Velocity of wave , `v = n lambda `
Wave length , `lambda = (v)/(n) = (240)/(160) = 1.5` m
