Solution

The correct option is B
Due to reflection of light

When we hold a mirror in sunlight, we see a bright patch of light on the wall opposite to the mirror. This is due to the reflection of light (sunlight) by the mirror. The reflection of light can be defined as the bouncing of light after striking a surface. The bounced light will fall on the wall and will form a bright patch on it.

We know that shiny, well polished surfaces like mirror reflect light well. We can also see our reflection in still water because it acts like a mirror. So if I make a laser light or any torch light fall on still water, will it reflect light? Plz explain the answer

Q. We see objects due to reflection but do we see light also due to reflection.

It is said that, when light hits a mirror and reflects, our mind predicts that it might be coming from a point opposite to the mirror. But when we use a camera to capture a image in the mirror, we see same as we see from our eyes. Why camera captures the same we see since it don't have brain to make it predict that light is coming from some other point?

A mirror reflects light and we humans are able to see ourselves in it. But we also know that we humans are opaque objects and do not let light pass through and a shadow is formed. So when we stand in front the mirror there should be a shadow on the mirror as we are opaque object but instead we see our reflection.WHY?

All practical mirrors absorb a little fraction of light incident on it. Due to this, when a ray of light is reflected repeatedly by a set of parallel plane mirrors, the intensity of the ray, after a few reflections, becomes :
