Doppler

Question

Due to Doppler effect, the shift in wavelength observed is $0.1 \overset{0}{A}$ , for a star producing a wavelength $6000 \overset{0}{A}$ . The velocity of recession of the star will be :

Moderate

Solution

$\begin{array}{l} \frac{V}{C} = \frac{Δ λ}{λ} \\ V = \frac{Δ λ}{λ} C = \frac{0.1}{6000} \times 3 \times 10^{8} = 5 \times 10^{3} m / s \end{array}$
