A wave of frequency 1000 Hz travels between X and Y. a distance of 600 m in 2 sec. How many wavelengths are there in distance XY.

A

3.3

B

300

C

180

D

2000

Text Solution

Verified by Experts

The correct Answer is:
D
`v=(600)/(2)=300 m//s`
`v=f lambda implies 300=1000xx lambda`
`implies lambda=(3)/(10)`m
`600=(3n)/(10) implies n=200xx10=2000`
