If you shine a single light source on a screen you will see that the entire screen is lit up. Assume this light source is of a s

ingle frequency (color). If you then turn on a second light source of this same frequency, and set it near the first, what will you see on the screen? (In practice, because visible light has such a short wavelength, the two light sources must be extremely close to each other.)

Answer:

An interference pattern.

Explanation:

When we have two light source of the same frequency turned on close to each other, the light emitted by them will interfere since light is also a wave. This means that an interference pattern will appear in a screen put ahead of them, that is, bands of light and darkness where the waves are interfering constructively and destructively.
