1.	The speed of light in air is 3xx10^8 m/s. Find its speed in diamond if the refractive index of diamond is 2.42 .
Answer» Solution :We know that `N="SPEED of light in air or vacuum (c )"/"speed of light in the medium (V )"` Here , n=2.42 and `c=3xx10^8` m/s `2.42=(3xx10^8)/v` `v=(3xx10^8)/2.42 =1.24 xx 10^8` m/s Thus, the speed of light in diamond has REDUCED considerably.
