If light waves are propagating in vacuum...

If light waves are propagating in vacuum, the relation between its frequency v, wavelength `lambda` and velocity C shall be

A

`v= Clambda`

B

`C= vlambda`

C

`lambda= vC`

D

`valpha lambda`

Text Solution

Verified by Experts

The correct Answer is:
B
Given that,
Frequency=v
Wavelength = `lambda`
We know that, `lambda` = travel distance in one cycle.
So, `lambda`= speed `xx` time
`= C xx T`
`C= vlambda :. [T= (1)/(v)]`
