A source of frequency 500 Hz emits waves...

A source of frequency `500 Hz` emits waves of wavelength `0.2 m`. How long does it take to travel `300 m` ?

A

70 s

B

60 s

C

12 s

D

3 s

Text Solution

Verified by Experts

The correct Answer is:
D
`v = v lamda = (500 Hz)(0.2 m) = 100 m//s`
Time taken by the wave to travel `300 m = (300 m)/(100 m//s) = 3 s`.
