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
- A \(\mathrm{C}\)
- B \(c+v\)
- C \(c-v\)
- D \(\sqrt{c^2+v^2}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{C}\)
Step-by-step Solution
Detailed explanation
The speed of light in vacuum is the same for any incrtial reference as \(c\left(3 \times 10^8 \mathrm{~m} / \mathrm{s}\right)\). This is true no matter how fast a light source is moving relative to an observer.
