Question

We can see the objects only when:
A) Reflected light from the objects reaches our eyes.
B) The object absorbs all the light.
C) When the objects allow all the light to pass through them.
D) None of the above.

Answer 1

The objects can be seen if and only if the objects either have their own light or they reflect the light coming from another source. Intensity of the light is more if the object is nearer and if the object is far away then the intensity of the object becomes less.

Step by step solution:
It is asked in the problem how we see objects.

There are two types of objects one which has their own light known as luminous objects and the objects which do not have their own light and known as non-luminous objects.

The luminous objects are those objects which have their own light like a bulb, the light coming out of the object gets to the lens of the human eye and the image of the object is formed on the retina of the eye and we can see the object.

The non-luminous object does not have light of their own and they can be only seen if they reflect the light from the other luminous objects. When the light strikes on the surface of the non-luminous objects then the objects reflect the light which is striking on them and the reflected light enters the lens of the human eye and the image is formed at the retina and the image of the object is formed and we can see the object. We can see the objects only when the reflected light from the objects reaches our eyes.

The correct answer for this problem is option A.

Note: The reflection of light is responsible for the visibility of most of the objects as every object is not luminous. If an object is luminous then the light from the object will be reflected from the lens and the image is formed at the retina.
