Question

How do we see object?

Answer 1

Few things are required to see objects.
(1) There should be some light source
(2) Light from a light source should fall on an object and the object should reflect light that falls on its surface.
(3) Light reflected from the object should reach our eye.
All three steps are a must for us to see the object.


For us to see an object, light from the source should fall on the object and then get reflected towards our eyes.
If there is no source of light, you won't be able to see an object.
The sun is the most important source of light, due to which we see objects in our surroundings.
