A star is moving away from earth with velocity of $100 km s^{- 1}$ . If the velocity of light is $3 \times 10^{8} m s^{- 1}$ , then shift of the spectral line of $λ = 5700 Å$ due to Doppler effect will be

Options:

Answer:

Solution:

In case of Dopplers effect in light waves

Using $∆ λ = \frac{υ}{c} \times λ = \frac{10^{5} \times 5700}{3 \times 10^{8}} = 1.90 Å$

$∆ λ =$ shift to spectral line
