Question

Refractive index can be defined for both transparent and opaque objects. True or false give reason? ????

Answer 1

yes........ its true... because refractive index can be noted for the materials those which allow the light to pass through them

Answer 2

Answer:

False. The Refractive index cannot be defined for both transparent and opaque objects

Explanation:

Based on the amount of light that materials transmit, they can be classified as transparent or opaque. Transparent materials are those that enable total light transmission. Pure glass is an example of a transparent substance. Whereas, opaque materials on other hand, do not allow light rays to penetrate through them. The light rays are either absorbed or reflected back into the environment. Materials such as wood, stone, and others are opaque.

Thus, Only those materials that can refract light, such as transparent objects, can be given a refractive index. Opaque objects are unable to refract light.
