Best Answer

An electron has dropped from a higher energy state to a lower one. The photon emitted has precisely the same energy as was lost by the electron.

How do you generate light?

Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.

Sketch an atom emitting light. Does the electron end up in a higher or lower orbit. Repeat for an atom absorbing light?

When an atom emits light an electron has fallen from a higher orbit to a lower orbit. The amount of energy the emitted photon has will equal the energy difference between the initial and final orbits.

The lines in the bright line spectrum of an atom are due to what?

The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.

Can light be bent or refracted when it hits a new material at a angle?

Light can only be bent by gravity, therefore, refraction occurs when light hits an atom's electron and is scattered in a different direction.

What is the change in atomic number when an atom emits a positron?

Emitting a positron, turns a proton into a neutron. So the atomic number goes down by 1, while the mass number remains the same.
