In a complete dark room why we can not see our face when we place a mirror in front of us explainit ?
Why we are not able to see in a dark room
1) We are not able to see our face in a cardboard but ,can see in plane mirror why?
2) A person uses a concave mirror while applying make-up on his/her face.
Instead of seeing our face in plane mirror when we see in transparent glass ,What happens?Does it reflect our face?
