1.A star producing light of wavelength 6000 A˚6000\,\text{Å}6000A˚ moves away from the earth with a speed of 5 km/s5\,\text{km/s}5km/s. Due to Doppler effect the shift in wavelength will be (c=3×108 m/sc = 3 \times 10^8\,\text{m/s}c=3×108m/s)a.0.1 A˚0.1\,\text{Å}0.1A˚b.0.05 A˚0.05\,\text{Å}0.05A˚c.0.2 A˚0.2\,\text{Å}0.2A˚d.1 A˚1\,\text{Å}1A˚Login to continueOnly logged in users canattempt or see the solution.
