Question

Doppler shifted hydrogen absorption lines are seen in the spectrum of a star. The hydrogen line at 656.28 nm is seen to be shifted to 656.08 nm. How large is the fractional shift in wavelength? Hint: fractional shift in wavelength = ? ? / ? . Here, ? ? is the small change or shift in wavelength and ? is the normal wavelength when the source is not moving. about 0.2 about 0.03 (3 E-2) about 0.000003 (or 3E-6) about 0.0003 ( or 3 E-4)

Doppler shifted hydrogen absorption lines are seen in the spectrum of a star. The hydrogen line at 656.28 nm is seen to be shifted to 656.08 nm. How large is the fractional shift in wavelength? Hint: fractional shift in wavelength = Δ λ / λ . Here, Δ λ is the small change or shift in wavelength and λ is the normal wavelength when the source is not moving. about 0.2 about 0.03 (3 E-2) about 0.000003 (or 3E-6) about 0.0003 ( or 3 E-4)
