## Question

### Solution

Correct option is

Going away from the earth with a speed 1. 5 × 107 ms–1

If a source emitting light of wavelength λ goes away from the earth, the apparent wavelength λ’ of the light reaching the earth is given by

Where v is the speed of the source of light and c the speed of light. The increase in wavelength âˆ†λ = λ' – λ is given by
