Study Notes

Light is a form of electromagnetic radiation that allows us to see objects and colors.

Polished surfaces are needed for reflecting light because they allow for specular reflection, resulting in a clear and undistorted image.
A mirror in scientific language is a reflective surface that bounces light back to our eyes, enabling us to see an image.

There are two types of mirrors: plane mirrors and curved mirrors, each with different properties and applications.

Mirrors are made by applying a thin layer of metal, usually aluminum or silver, to one side of a pane of glass.

The sensation of vision occurs when light from an object is reflected into our eyes, allowing us to perceive the object.
Rough surfaces cause diffuse reflection, scattering light in all directions and making it difficult to see a clear image.
Polished surfaces are essential for mirrors to produce a clear and undistorted reflection.
