choose the correct option. If speed of gamma rays, X-rays and microwaves are `V_(g),V_(x)" and "V_(m)`.

Options

A. `V_(g)gtV_(x)gtV_(m)`
B. `V_(g)=V_(x)=V_(m)`
C. `V_(g)ltV_(x)ltV_(m)`
D. `V_(g)gtV_(x)ltV_(m)`

Answer

B

Explanation

The speed of electromagnetic waves remain the same in a medium irrespective of their wavelength. All electromagnetic waves travel with the speed light of light in vacuum.
`:.V_(g)=V_(x)=V_(m)`
