Earth is moving towards a fixed star with a velocity of 30 kms^(-1) . An observer on earth observes a shift of 0.58 Å in wavelength of light coming from star. What is the actual wavelength of light emitted by star ?

Earth is moving towards a fixed star with a velocity of 30 kms^(-1) . An oberver on earth observes a shift of 0.58 Å in wavelength of light coming from star. What is the actual wavelength of light emitted by star ?

A star is moving away from the obsever on the Earth with a speed of 400 km/s. What will be the Doppler shift if the wavelength of light emitted by the star is 5800 Å ?

The apparent wavelength of light from a star moving away from earth is observed to be 0.01% more than its real wavelength. The velocity of star is

A star is moving away from the Earth with speed V. Change in wavelength (dlambda) observed on Earth is
