(3) When are things seen by us? I am in 7th class ​

Answer 1

Answer:

The light coming from the source falls on the object and reflects back into our eyes and our eye lens form an image of it which is virtual and inverted..but our brain interprets correctly..so we see the objects.

Answer 2

As we all know that,

• we can see any things in light only.
• we can not see anything in dark.
• It's is all due to reflection of light .

》Let's us understand how reflection of light works in seeing any objects.

• when any thing is placed in light the light rays coming from the sun which is ultimate source of energy and light or emitter that is bulb .

• The rays coming from them moves to the objects and get reflected after that the reflected rays come to our eyes in contact with eye lens and the image formed on retina.

• The image send to brain through electrical signals and brain analyze it and in this way we can see objects .
