If a star emitting yellow light is accelerated towards earth, them to an observer on earth it will appear

Options

  1. Abecoming orange
  2. Bshining yellow
  3. Cgradually changing to blue
  4. Dgradually changing to red

Correct answer

C. gradually changing to blue

Step-by-step solution

Since, Doppler’s effect for light when source approaches t = c + u c - u (Since, f > f y e l l o w ) So, there will be blue shift
