Question

Define refraction. Explain any two situation at curved surfaces where

refraction occurs with neat diagram.​

Answer 1

Answer:

refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.[

Answer 2

Explanation:

the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.

change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.

measurement of the focusing characteristics of an eye or eyes.

There is an object O and a ray of light from the object O is incident on the spherical mirror. Since it is moving from a rarer medium to a denser medium, the ray bends towards the normal.

the refraction of light at the spherical surface. Now, the change in direction or bending of a light wave passing from one transparent medium to another caused by the change in wave’s speed is the Refraction. Suppose the above figure is a spherical surface. There is one medium with refractive index n1 and second medium with refractive index n2.

There is an object O and a ray of light from the object O is incident on the spherical mirror. Since it is moving from a rarer medium to a denser medium, the ray bends towards the normal. An image is formed and radius of curvature of a spherical surface is R with the center C of the spherical surface
