Question

What is the difference between refraction of light and total internal reflection of light?

Answer 1

Explanation:

Reflection and total internal reflection are very important physical properties of waves. In general, when a wave strikes on an object, the resulting change of the direction of the wave is called reflection. The most important and known fact about the reflection is the ability to see objects when light rays reflected from the object to the eye. In fact, the total internal reflection is mostly discussed under the reflection of light. There are many technical usages of wave reflection and total internal reflection such as ultra sound technology and sonar technology and fiber optics respectively. Since this is a broad area of wave mechanics, in this discussion, we are going to discuss mainly about reflection and total internal reflection of light and reflection laws of light briefly.

please mark as brainliest ☺️

Answer 2

Explanation:

refraction of light means the light ray travel from one medium to another medium

but total internal reflection means light ray incident on interfence and return back to same medium
