Question

why we use a plane mirror to see our face.

Answer 1

hey!
Plane mirror causes regular reflection of light.
When a parallel beam of light is incident on a plane mirror it is reflected back parallely.
Due to this property a plane mirror is used to see our image and not a rough surface...

Answer 2

A plane mirror is used to see our face because it reflects an image of our face back to us in a way that allows us to see ourselves clearly.

• A plane mirror is just a flat piece of glass or metal that has been coated with a thin layer of metal, typically aluminum or silver, which allows it to reflect light. When light from our face strikes the surface of the mirror, it bounces back to our eyes in a way that allows us to see a clear image of our face. The angle of incidence and the angle of reflection are equal, creating a virtual image, which is flipped horizontally.
• But it's not just our faces that we use plane mirrors for. They have a wide range of applications, from cars and buildings to optical instruments like telescopes and cameras. They are truly a marvel of physics and human ingenuity.
