Two Cu wires of radii R(1) and R(2) are ...

Two Cu wires of radii `R_(1)` and `R_(2)` are such that `(R_(1) gt R_(2))` . Then which of the following is true ?

A

Transverse wave travels faster in thicker wire

B

Transverse wave travels faster in thinner wire

C

Travels with the same speed in both the wires

D

Does not travel

Text Solution

Verified by Experts

The correct Answer is:
B
The velocity of a transverse wave
`v = sqrt((T)/(rho A))`
` v prop (1)/(sqrtA)`
or ` v prop (1)/(R)`
Because the velocity of wire depend on the radius . So transverse wave travels faster in thinner wire.
