Question

what is important in this refection and refraction of light... ​

Answer 1

Answer:

Reflection and refraction. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The reflected ray is always in the plane defined by the incident ray and the normal to the surface.

And this is important beacuse we cannot see anything if there would be no reflection and refraction

Hence, it plays a very crucial role in our life

Answer 2

ᗩᑎՏᗯᗴᖇ

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

DIFFERENCE BETWEEN THEM ::---

The basic difference between reflection and refraction is that Reflection of light is the process in which light bounces back on striking the surface, while refraction of light is the process in which light changes its direction as it passes from one medium to another medium.

what is important in them??

answer ︎:--

Reflection and refraction. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. ... The law of reflection can be used to understand the images produced by plane and curved mirrors.
