Prove 2nd law of reflection that angle of incidence =. Angle of reflection .......Pls do not use Fermat's principle........

Answers

Answered by mayank3819

2nd law of reflection say that angle of incidence=angle of reflection because the distance between angle-i and angle-r is same and all of them lies in same plane

mayank3819: plane mirror means

mayank3819: then i will tell u it is a regular or irregular reflection

mayank3819: it is why because plane mirror is smooth surface regular reflection occurs in it

mayank3819: if we draw an incident ray in plane mirror it will go in same direction named as reflection ray and if we draw a normal it is considerd as angle-i=angle-r

mayank3819: u understand this

viniaradhy: I understand but iska koi mathematically derivation nhi hai

mayank3819: nhi ye sirf plane mirror mai hota h aap isko

mayank3819: samajh sakte ho iska koi mathematical ans nhi hota h

viniaradhy: Ok...... ..

viniaradhy: Thanks
