$\bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{\:ANSWER}}}}}}}}}}$


$\Large\bold\star\underline{\underline\textbf{Diamond's Brilliance\:}}$

→ Brilliance of diamond is due to total internal reflection of light.

→ The refractive index for diamond is 2.42. Therefore, the critical angle for diamond at air interface is,

» Sin C = 1 / n

» = 1 / 2.42

» = 0.4132

→ C = 24.40°


→ The diamond is cut suitably so that light entering the diamond from any face falls at an angle greater than24.4°. Hence, light suffers multiple total internal reflections at the various faces.

→ In the end, the light emerges out from some place in certain directions. This makes the diamond to sparkle.
