How does light behave when moving from one medium to another, such as passing through glass?

Why does a rainbow arc form when light is refracted as if falling to the ground?

What causes the shimmering beauty of a rainbow according to the text?

In everyday life, where can we observe refraction happening?

What happens to the direction of light when it enters water from air?

How do raindrops contribute to the formation of a rainbow?

What would happen if light did not slow down when entering water?

Light is an electromagnetic wave that travels through space. When light passes through air, it slows down; when it enters water, it speeds up. This difference in speed of light between different materials allows us to see objects underwater—if the material was opaque like land, we would only be able to see so far. As light moves from one medium into another, such as passing through glass, the direction of its path changes slightly because the waves slow down more than they bend. This change of direction is called refraction.

Refraction occurs whenever there's a change in what kind of matter light goes through. It takes place at every interface where something changes, like going into water from air. If you think of light as if it were falling, then it bends just before reaching the ground, forming a rainbow arc. A rainbow creates itself by making sunlight go around corners. In other words, the raindrops cause the light to bend this way and that upon entering them. They also send some colors off in new directions while letting others continue straight ahead. So, you can say that refraction helps make the shimmering beauty of a rainbow possible.

In everyday life, refractions occur all around us. For instance, when we look through the window or a camera lens, light bends according to how much slower it is inside the object. Also, when we put our hand over part of an image projected onto paper, some parts become darker due to refraction caused by the hand blocking light rays coming out of the projector. Through these actions, we experience firsthand a natural phenomenon known as refraction, which causes light to bend when moving from one substance to another.

Test your knowledge about the concept of light refraction and how it affects the path of light when moving from one medium to another. Learn about the reasons behind rainbows, the bending of light through various materials, and common scenarios where refraction occurs in daily life.
