# When a ray of light travels from air to glass and strikes the surface of separation at 90 then it?

## When a ray of light travels from air to glass and strikes the surface of separation at?

When a ray of light travels from air to glass slab and strikes the surface of separation at 90∘, then it. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

## When a light ray makes an angle of 90 degree while entering a glass slab from air it?

Explanation: Refraction is the process of bending of light as it moves from one medium to another. When light ray from air in incident to a glass slab at any angle except 90 degrees, refraction occurs and the light ray bends towards the normal.

## Can total internal reflection occurs when light travels from rarer to denser medium?

When light travels from a rarer to denser medium it bends towards the normal, the condition for total internal reflection requires the ray to bend away from the normal till 90 degree angle is attained. Hence it will not be a case of rarer to denser medium refraction.

## What happens when a ray of light enters into a denser medium from a real one?

Refraction of Light: as it passes from less dense to more dense mediums. When light passes from a less dense to a more dense substance, (for example passing from air into water), the light is refracted (or bent) towards the normal.

## Does light travel faster in less dense medium?

When light enters a denser medium (like from air to glass) the speed and wavelength of the light wave decrease while the frequency stays the same. Light moves slower through denser media because more particles get in its way.

## How do you know which medium is more dense?

A medium in which speed of light is more is known as optically rarer medium and a medium in which speed of light is less is said to be optically denser medium. For example in air and water, air is raer and water is a denser medium.

## What happens to light as it passes from a less dense to a more dense medium?

Light is refracted (bent) only at the interface between two transparent materials of different density. Light passing from a less dense to a more dense medium bends toward the normal. Light passing from a more dense to a less dense medium bends away from the normal.

## What happens to light as it moves from a faster medium to a slower medium?

Light Traveling from a Fast to a Slow Medium If a ray of light passes across the boundary from a material in which it travels fast into a material in which travels slower, then the light ray will bend towards the normal line.

## Is denser or rarer nature relative or absolute?

given the refractive index of air,glass,kerosene,diamonds are 1,1.4,1.44 and 2.42 respectively. It is absolute. Diamonds, kerosene, glass ,air. b) Denser are rarer is a relative term.
