When an electron goes from a higher energy level back down to the ground state, what is the most accurate way to describe the light it emits? always a single photon, with less energy than the electron absorbed to move up to the higher level. the electron does not emit light but absorbs light. one or more photons, always with less total energy than the energy the electron absorbed to move up to the higher level. always a single photon, equal in energy to the energy the electron absorbed to move up to the higher level. one or more photons, equal in total energy to the energy the electron absorbed to move up to the higher level.

One photon, same energy.

Explanation:

When an electron goes from a higher energy level back down to the ground state the most accurate way to describe the light it emits is always a single photon, equal in energy to the energy the electron absorbed to move up to the higher level, since the energy between levels is already determined, and in these cases is always only one photon that is emitted or absorbed.

i wanna say it’s between b and d, leaning more towards b.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
