If V(g),V(x) and V(m) are the speeds of ...

If `V_(g)`,`V_(x)` and `V_(m)` are the speeds of gamma rays, x-rays and microwaves respectively in vacuum then

A

`v _(gamma) gy v _(X) gt v_(m)`

B

`v _(gamma) lt v _(X) lt v _(m)`

C

`v _(gamma) gt v _(X) lt v _(m)`

D

`v _(X) =v _(gamma) = v _(m)`

Text Solution

Verified by Experts

The correct Answer is:
D
In vecuum, electromagnetic waves travel with the same speed i.e., the speed of light `(3xx 10 ^(8) m//s).`
`therefore v _(gamma) = v _(X) = v _(m)`
