If we want to study rest-frame visible light emitted by stars in distant galaxies at a high redshift of z 3, what portion of the electromagnetic spectrum do we need to observe? (hint JWST is meant to study distant galaxies)

Respuesta :

The  portion of the electromagnetic spectrum do we need to observe is the red part of the This is further explained below.

What is electromagnetic spectrum?

Generally, Spectrum refers to the range of wavelengths or frequencies that electromagnetic radiation may cover.

In conclusion, We need to keep an eye on the red part of the electromagnetic spectrum since a large positive redshift causes an increase in wavelength and a corresponding fall in frequency and photon energy (such as light).
