Question: Three observers A, B and C measure the speed of light coming from a source to be ${v_A}$, ${v_B}$ and ${v_C}$. The observer A moves towards the source, the observer C moves away from the source with the same speed. The observer B stays stationary. the surrounding space is vacuum every where. Then


1) ${v_A} > {v_B} > {v_C}$
2) ${v_A} < {v_B} < {v_C}$
3) ${v_A} = {v_B} = {v_C}$
4) ${v_A} = {v_B} > {v_C}$
Solution: Explanation: No Explanation
