Shadow characteristics
The farther the object is away from the light source, the smaller it is on the screen. When the screen and light source are stable and the object is moving.
The closer the light source is, the bigger the object's shadow gets. When the screen and the object are stationary.
The farther the screen is away from the object, the bigger it gets.

When reflected light rays reach our eyes, we see an image.
Real images - light rays actually meet to produce the image. can be formed on screens and projected.
-
DISPERSION
When the speed of light of different light rays slows down inconsistently when it goes through a prism. This forms a spectrum.
Rainbows are formed when the light from the sun is reflected back from raindrops or any other water source.
