Graph shows three waves that are separately sent along a string that is stretched under a certain tension along x-axis. If `omega_(1),omega_(2) and omega_(3)` are their angular frequencies, respectively, then:

A

`omega_(1)=omega_(3)gtomega_(2)`

B

`omega_(1)gtomega_(2)gtomega_(3)`

C

`omega_(2)gtomega_(1)=omega_(3)`

D

`omega_(1)=omega_(2)=omega_(3)`

Text Solution

Verified by Experts

The correct Answer is:
a
As `f _(1)=f_(2),f_(2)=(f)/(2),f_(3)=f`
`:.Omega_(1)=2pifimplies Omega_(3)=2pif and Omega_(2)=pif`
