Question

How are things visible to us?
A. Light gets reflected from our eyes and makes the object visible.
B. Light from the object gets reflected and makes the object visible.
C. Both A and B can occur according to the light condition
D. The reason is still not known.

Answer 1

Hint: We are able to see any object because light from an object can move through space and reach our eyes. Once light reaches our eyes, signals are sent to our brain, and our brain decodes the information in order to detect the appearance, location and movements of the objects, we are looking at.

Complete Step-by-Step solution:
We have to explain how the objects are visible.
Now, we know that light is the source which makes things visible to us. If there is no light, we cannot see anything around us.
When light falls on any object then the light gets reflected or bounces back to our eyes and it becomes visible. Without reflection occurring it won’t be visible to us.
As, when light coming from the source falls on the object, it gets reflected back to our eyes and our eye lens forms an image of it which is virtual, erect but of the same size as the object.
Hence, the correct option is B.

Note – For these types of questions, always think that if there is no light, we can’t see any object, also if the object does not reflect the light falling on it then the object will not be visible. As, mentioned in the solution option B is therefore correct. Always keep in mind that the objects we see are visible to us because of the reflection. When light falls on an object then the light bounces back to our eyes and things are visible to us.
