Q3) [12+ 4 = 16 Marks] A rocket approaching Earth at velocity v has a headlight which is seen by an observer on Earth to have wavelength A₁. After the rocket passes the Earth it recedes with the same velocity and the rocket's taillight (which is physically identical to the headlight) is observed on Earth to have a wavelength ₂. a) If 2₂=2A, then what is 2 b) If 450nm, then what is the wavelength as measured by an observer onboard the rocket?
