(i) The refractive index of Ruby stone is 1.71. What is meant by this ...
Explanation of Refractive Index:
The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium. It is a measure of how much the speed of light is slowed down as it passes through a medium.

Answer to part (i):
The statement "The refractive index of Ruby stone is 1.71" means that when light passes through Ruby stone, it is slowed down by a factor of 1.71 compared to its speed in vacuum.

Answer to part (ii):
(a) The speed of light is maximum in a medium with the lowest refractive index. Therefore, the speed of light is maximum in water with a refractive index of 1.33.

(b) The speed of light is minimum in a medium with the highest refractive index. Therefore, the speed of light is minimum in Sapphire with a refractive index of 1.77.

Summary:
- Refractive index is the ratio of the speed of light in vacuum to the speed of light in a medium.
- The refractive index of Ruby stone is 1.71, which means that light passing through it is slowed down by a factor of 1.71 compared to its speed in vacuum.
- The speed of light is maximum in water with a refractive index of 1.33 and minimum in Sapphire with a refractive index of 1.77.

(i) The refractive index of Ruby stone is 1.71. What is meant by this ...
1)This means that the ratio of speed of light in ruby to that of speed of light in vaccum is 1.71
2) maximum = glass >water > sapphire
for minimum u can reverse ,,;
