Question

please solve it for me it's very important for me please answer to very fast I will make you brain list

Answer 1

Hlo
============================================
here is ur answer
=======================================
acc. to snell's law
refractive index=sin i/sin r
                        =sin60°/sin15°
                        =0.866/0.258
                        =3.35
======================================
HOPE IT WILL HELP U

Answer 2

a light is traveling in a medium.. whose angke is 60° and deviates from its path with 15°....

a/q Snell's ,, sin of angle of incidence /sign of angle of refraction =constant
and this constant us called refractive index

=> 60°/15°
=> sin 60= 0.8660
sin15°= 0.2588
=> 3.346 (ans)
it doesn't have any S.I unit .....

hope it helps frnd!! :( => :)...
