Question

why angle i=angle r ,under reflection

Answer 1

it is experimental it can't be calculated

Answer 2

Hey mate!

Here is your answer.....

• As we know, lights travels in a straight line.

• Because, light always choses the quickest path.. not the shortest path!

<> So, when light falls on a surface (incident ray)... then, it reflects (reflected ray)

<> If we draw a noramal... then we can see the equal angle!

Hope it helps u..
