The specific pattern of colors emitted by excited atoms is called a
rainbow.
cathode ray.
continuous spectrum.
line spectrum.

It is called a line spectrum.

Explanation:

When an atom jumps from one energy level to a higher one, it is said that it is in an excited state.

As the normal behavior is to be at a ground energy level (unexcited state), the atom tries to return to this state as soon as possible.

When doing this, it emits a photon of a distinct wavelength, which depends on the transition type.

As there are only some allowed transitions possible, the possible wavelengths are a discrete set too.

So, when projected on a photosensitive screen, the different colors form a set of discrete lines, so this specific pattern of colors is called a line spectrum.
