A sound wave having a frequency of 500 H...

A sound wave having a frequency of 500 Hz travels with a velocity of 360 m/s. What is the distance between two particles on this wave, who have a phase difference of `60^(@)` ?

A

5 cm

B

12 cm

C

50 cm

D

4.24 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`lamda = (36000)/(500) = 72 cm` Phase diff. `= (2pi)/(lamda)` (path diff)
`(pi)/(3) = (2pi x)/(72) :. 6x = 72 :. x = 12cm`
