Given, critical angle (n) of the diamond is 24°.
then its absolute refractive index is                                                                                                                              n= 1/sin c                                                                                                         n= 1/sin  24°                                                                                                       n= 1/-0.905                                                                                                       n= -1.104
plzzzzzzzz say thanks and mark it as best if it helps u
plzzzzzzzzz mark it as best friend
How come refractive index is negative?
sorry thats positive. i note that by mistake
plzzzzzzzzz mark it as best

Absolute refractive index
n=1/sin c
n=1/sin 24
n=1/-0.905
n=   -1.104
How come refractive index is negative?
sorry thats positive. i note that by mistake
