Two waves gives by `y_(1)=10sinomegat` cm and `y_(2)=10sin(omegat+(pi)/(3))` cm are superimposed. What is the amplitude of the resultannt wave?

A

10 cm

B

`10sqrt(2)cm`

C

`5sqrt(3)cm`

D

`10sqrt(3)cm`

Text Solution

Verified by Experts

The correct Answer is:
D
Amplitude `=R=2A_(0)"cos"(phi)/(2)=2xx10xxcos((pi)/(6))`
`=20xx(sqrt(3))/(2)xx10sqrt(3)cm`
