Step-by-step solution
z = (λ−λ₀)/λ₀
What Is Redshift?
Redshift is the stretching of the wavelength of a light source moving away from us. It is used to measure the recession velocity and distance of galaxies.
How is it calculated?
How Is It Calculated?
z = (λ_observed − λ_source) ÷ λ_source
- Enter the observed and source wavelengths.
The larger z is, the farther away and faster the object is receding.
Frequently Asked Questions
Can blueshift occur too?
Yes; for sources approaching us the wavelength shortens, which is called blueshift.
