Light from a source travels out with a velocity (c ). If the source moves away from the observer with a velocity (v ), then the relative velocity of light with respect to observer is

Options

  1. A( C )
  2. B(c+v )
  3. C(c-v )
  4. D( c^2+v^2 )

Correct answer

A. ( C )

Step-by-step solution

The speed of light in vacuum is the same for any incrtial reference as (c (3 10^8 ~m / s ) ). This is true no matter how fast a light source is moving relative to an observer.
