Brilliance of diamond is due to

Text Solution

Verified by Experts

The refractive index of a diamond is 2.42 and the critical angle for diamond is given by
`sin C =(1)/(mu)=(1)/(2.42)=0.4132`
or C = 24.4
As the value of critical angle is very small so the diamond is cut in such a way that it has multiple faces at suitable angles. A ray of light on entering into the diamond suffers total internal reflection from other faces and comes out of the diamond as an intense beam from selected directions and the faces shine when viewed from outside.

Sparking Brilliance of Diamond: The total internal reflection of the light is used in polishing diamonds to create a sparking brilliance. By polishing the diamond with specific cuts, it is adjusted the most of the light rays approaching the surface are incident with an angle of incidence more than critical angle. Hence, they suffer multiple reflections and ultimately come out of diamond from the top. This gives the diamond a sparking brilliance. The following diagram shows same diamond cut in two different shapes. The brilliance of diamond in the second diamond will be:

Hence, they suffer multiple reflections and ultimately come out of diamond from the top. This gives the diamond a sparking brilliance. Light cannot easily escape a diamond without multiple internal reflections. This is because:

By polishing the diamond with specific cuts, it is adjusted the most of the light rays approaching the surface are incident with an angle of incidence more than critical angle. Hence, they suffer multiple reflections and ultimately come out of diamond from the top. This gives the diamond a sparking brilliance. The basic reason for the extraordinary sparkle of suitably cut diamond is that
