Question

The refractive index of diamond is ______.

Options

• 2.42

• 1.54

• 1.36

• 1.50

Answer 1

The refractive index of diamond is 2.42.

Explanation:

• Diamond has a refractive index of about 2.42, which is significantly greater than that of ordinary materials such as glass or water.
• This high refractive index accounts for diamond’s spectacular sparkle and remarkable light-bending properties.
• The remaining options (1.54, 1.36, 1.50) correspond to materials such as glass (about 1.5) or other substances, but not diamond.
