if the speed of light in the medium is 1.5 into 10 raise to power 8 metre per second what is the absolute refractive index of the medium |
|
Answer» Answer : the absolute refractive INDEX of the medium is 2 Explanation : v = c / u where c is the SPEED of LIGHT in vacuum u is the absolute refractive index of the medium and v is the speed of the light in that medium So, u = c / v c = 3 x 10 ^ 8 m/s v = 1.5 x 10 ^ 8 m/s given => u = 3 x 10 ^ 8/ 1.5 x 10 ^ 8 = 3 / 1.5 = 2 |
