Question

what is refraction ​

Answer 1

Answer:

the change in the direction of path of light ray when it passes from one transperent medium to another transperent medium is called refraction of light.

I hope it works :-)

Answer 2

$\bf Reflection$

Refraction is a phenomenon which happens when a ray of light passes from one transparent medium to another. For refraction to take place, it Refraction of Light is important that both the media have different densities. Refraction can also take place in the same media if the densities of different layers vary. Focal point

When a ray of light passes from one transparent medium to another transparent medium, there is a change in its direction. This change in direction due to speed of light in different mediums is called refraction. There are certain rules that are followed by light during refraction.

➵ When light travels from a rarer to a denser medium, it bends towards the normal.

➵ When light travels from a denser to a rarer medium, it bends away from the normal.

➵ When light travels along the normal, there is no deviation, that is, the ray suffers no refraction.
