1:49 Refractive index is the ability of a material to bend the light.
4:43 Refractive index of a material is directly proportional to bending of the light and 6:12 Optical density.
And 9:24 inversely proportional to the speed of light.
It is not right sir. Medium having reflective index 0.5 and 1.5 have the same bending of light
0.5and 2
Thanks bro ❤
26:20, Refractive index of 'Z' with respect to 'X' is 9/8.
haa yahi answer hai
