Question

Luminous objects such as flashlights emit light that we can see. How do we see an object that isn’t luminous?

Answer 1

The object which are not luminous  are observed by the light reflected off the object and reaches our eyes.

Option B

Explanation:

A non-luminous object reflects light from its surface that is incident on it from some other luminous source or body, to be seen by the naked eye as a whole. The light reflected, reaches the observer’s eyes and is viewed as a result.

Non-luminous objects never emit their light, rather they are dependent on luminous objects to be seen by the observer. A piece of cloth, moon, earth, wood, plastics, metals, etc. are some fundamental examples of a non-luminous object.

Answer 2

B is the correct answer.
