A wave in slinky travelled to and fro in 5 s. The length of the slinky is 5 m, then velocity of wave is

A

10 m/s

B

5 m/s

C

2 m/s

D

25 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
Time taken to travel to and fro = 5 s , length = 5 m .
so, time taken to go / come back = 5 / 2 s
`:.` Velocity of the wave `= (5)/(5//2)` = 2 m/s
