Question

How can materials classified based on the amount of light that passes through them ?​

Answer 1

Answer:

Materials can be classified according to the amount and type of light they transmit. Transparent (trans-PAIR-uhnt) materials allow most of the light that strikes them to pass through. ... Opaque (oh-PAYK) materials do not allow any light to pass through them, because they reflect light, absorb light, or both.

Answer 2

Transparent, Opaque, and Translucent materials can be classed based on the quantity of light they transmit.

• Transparent substances allow light rays to flow through.
• Transparent substances have a refractive index that is almost equal.
• Snell's law of refraction governs light rays.
• The quantity of dispersion when going through a transparent object is quite low. As a result, on the other side of the substance, a clear image is visible. Examples: Lenses, spherical mirrors, spectacles etc.
• If a substance allows for partial transmission of light rays, it is considered transparent. In the interior of such objects, light rays are scattered. As a result, light beams emerge in random directions. The image of any item seen through a translucent material seems blurred.  Examples: butter paper, tissue, plastic cups etc.
• Light does not travel through opaque materials. Any light that strikes the surface is totally scattered, reflected, or absorbed. Examples: Wood, Concrete, Metals etc.
