Question

The hydrogen-alpha spectral line of a certain star is observed on Earth to be "redshifted" from a wavelength of 656.28 nm to a wavelength of 773.80 nm. Interpreting this as the Doppler effect for light, calculate the speed and direction (approaching or receding) of this star's movement relative to the Earth.

Step 1

Given: Initial wavelength, λ1 = 656.28 nm Final wavelength, λ2 = 773.80 nm Change in wavelength = λ2 - λ1 Change in wavelength = 773.80 nm - 656.28 nm Change in wavelength = 117.52 nm Show more…
