Question:

If $v_s, v_x \, and\, v_m$ are the speeds of gamma rays, X-rays and microwaves respectively in vacuum, then

Options:

$v_s > v_x > v_m$

$v_s < v_x < v_m$

$v_s < v_x > v_m$

$v_s = v_x = v_m$

Correct Answer:

$v_s = v_x = v_m$

Explanation:

Velocity of wave depends only on electric and magnetic property of the medium so its equal to all the waves.
