Prove that for any relative velocity v between two observers, a beam of light sent from one to the other will approach at speed c (provided that v is less than c, of course).

To determine

To show:

That if relative velocity between observer is vthen the speed of light sent from one observer to other approaches to c.

Explanation

Given info:

• The relative velocity between observers is v.
• The relative velocity of the beam with respect to one observer is c.

Formula used:

The formula to find the velocity of the beam relative to the second observer is.

u=u'+v1+vu'c2

Here, uis the velocity of the beam relative to the second observer, vthe relative velocity of the observers, u'is the velocity of the beam with respect the first observer and cis the speed of light
