Answer 2

The principle behind the sparkling of diamonds is Total Internal Reflection. (Option a)

• Total internal reflection is a complete reflection of a ray of light within a medium such as glass or water from the surfaces around and back into the medium.
• The phenomenon occurs only if the angle of incidence is greater than a certain angle, called the critical angle.
• An example of total internal reflection is a diamond. Diamonds achieve their brilliance and sparkle partially from total internal reflection.
• It has the highest refractive index but can increase the amount of total internal reflection by being cut into proper ratios making diamond sparkle.
