A string of length 0.4 m and mass `10 ^(-2)` kg is tightly clamped at its ends. The tension in the string is 1. 6 N. identical wave pulses are produced at one end at equal intervals of time `Delta t`. The value of `Delta t` which allows construction tnterference betwenn successive pulses is

A

0.05s

B

0.10s

C

0.20s

D

0.40s

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity of wave :`v=sqrt((T)/(m))=sqrt((1.6)/(10^(-2)//0.4))=8 m//s`
The wave wil be in same phase after traveling a distance at of ` 21 =2xx0.4=0.8m` and distance interfernce will take place. So time `trianglet`
`trianglet=(0.8)/(v)=(0.8)/(8)=0.10 s`
