As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal.
But why does the light appear to bend and refract?
Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal.
I hope this helped. :)

How is a miterial's index of refraction related to its optical density?
A material's index of refraction is related to its optical density through Snell's Law, which relates the angles of incidence and refraction as light passes through the interface between two materials with different refractive indices. A higher index of refraction usually corresponds to a higher optical density, meaning that light travels slower through the material.
How is trignometry used in optics?
Optics deals with refraction - the bending of light rays as they go from a medium of one optical density to another - as in an optical lens. Given the refractive indices of the two materials, the angle of refraction is related to the sine of the angle of incidence.
Does light refraction increase during distance vision?
No, light refraction does not increase during distance vision. Light refraction occurs when light travels from one medium to another of different optical density, causing it to change direction. The amount of refraction is determined by the difference in optical density between the two mediums, not by the distance of the object being viewed.
What does light bend when it passes from air into glass?
refraction
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
The bending of a wave as it passes an angle from one medium to another?
The bending of a wave as it passes through an angle from one medium to another is known as refraction. Refraction occurs due to a change in the speed of the wave as it moves from a medium with one optical density to another with a different optical density, causing the wave to change direction.
What is the bending of light from one medium to another?
The bending of light as it passes from one medium to another is called refraction. This phenomenon occurs because light changes speed as it moves from a medium with one optical density to another. The angle at which light bends depends on the change in optical density between the two mediums.
What allows light to pass through but not in a straight path?
This physical phenomenon is called refraction.
Why is refractive index of light necessary?
it is necessary to identify the optical density of a particular medium air for example is 1.00 and the refraction in a medium can be figured out by sinøincidence ÷ sinø refraction
What does refraction means in a definition?
Refraction refers to the bending of light as it passes from one medium to another of different optical density, such as air to water, causing a change in the light's direction.
When light is bent as it travels through an object it is called?
Refraction. This is when light changes direction as it passes from one transparent medium to another with a different optical density, causing it to bend.
What causes refraction and what is it?
Refraction is the bending of light as it passes from one medium to another with a different optical density. This bending occurs due to the change in the speed of light as it moves through materials of varying density. Refraction causes phenomena such as the bending of a pencil in a glass of water and the formation of rainbows in the sky.
