Question

What is refraction of light?​

Answer 1

The phenomenon of the change of the light path from one medium to another in case of transparent medium is known as refraction of light .

Firstly , the incident ray enters the medium 1 then it got refracted in medium 2 coming outward .

It's Laws :-

• The incident ray, refracted ray & the normal to the interface at the point of incidence all lie in same plane normal to the surface .

• The ratio of sin incidence and the ratio of sin reflection is 1mew2.

Refractive index = speed of light in vacuum / speed of light in medium.

Answer:

Refraction Explanation

Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.

Defining Refraction

“Refraction is the change in the direction of a wave passing from one medium to another.”

                Refraction of light is one of the most commonly observed phenomena, but other waves like sound waves and water waves also experience refraction. Refraction makes it possible for us to have optical instruments such as magnifying glasses, lenses and prisms. It is also because of the refraction of light that we are able to focus light on to our retina.

Laws of Refraction of Light

Laws of refraction state that:

• The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.

• The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

                                               $\frac{sin\;i}{sin\;r}=constant$
