Calculate the refractive index of the material of a glass slab. Given that the speed of light through the glass slab is 2 xx 10^(8) m//s and in air is 3 xx 10A^(8) m//s. |
|
Answer» Solution :As per QUESTION speed of light in air `c = 3 xx 10^(8) m s^(-1)` and speed of light through the glass slab `v = 2 xx 10^(8) m S^(-1)` `therefore`REFRACTIVE index of glassslab n = `(c )/(v)=(3xx10^(8))/(2XX10^(8))=1.5` |
