How do you explain refraction?

refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow.

What is formed when the light from the sun passes through raindrops?

Sunlight passing through raindrops causes rainbows via a process called refraction, which is the bending of light as it passes from one medium to another.

How do you introduce refraction of light?

When electromagnetic radiation, in the form of visible light, travels from one substance or medium into another, the light waves may undergo a phenomenon known as refraction, which is manifested by a bending or change in direction of the light.

Why does light bend during refraction kids?

The bending is caused due to differences in density between the two mediums. When the light passes from more dense medium to less dense medium, the light refracts in reverse direction and vice versa.

Does a rainbow actually touch the ground?

A rainbow is formed when light from the sun meets raindrops in the air and the raindrops separate out all these different colours. Because rainbows are made in the sky, they don’t touch the ground. You can also sometimes see miniature rainbows in your garden if you’re watering your plants with the sun behind you…

Who discovered the refraction of light?

Willebrord Snel van Royen
Willebrord Snell, Latin-Dutch Willebrordus Snellius, original name Willebrord Snel van Royen, (born 1580?, Leiden, Netherlands—died October 30, 1626, Leiden), astronomer and mathematician who discovered the law of refraction, which relates the degree of the bending of light to the properties of the refractive material.

Why pencil looks broken in a glass of water?

As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes medium and subsequently undergoes refraction. As a result, the image of the pencil appears to be broken.
