What would be the observed wavelength for the Balmer H$\alpha$ line emitted at 486.1 nm by a quasar at redshift z =5?
A) 2.9 µm
B) 81.0 nm
C) 21.0 cm
D) 121.6 nm
E) 1.2 µm

Question

Quizplus · Accepted Answer

The observed wavelength is calculated using the formula: observed wavelength = emitted wavelength * (1 + redshift). For a redshift z = 5, the observed wavelength is 486.1 nm * (1 + 5) = 2916.6 nm, which is equivalent to 2.9 µm.
