Difference between Mirror and Lens

Difference Between Mirror and Lens

Even though both these devices are used in optics, there is a difference between mirror and lens. The mirror is a device based on the principle of reflection whereas the lens is based on the principle of refraction. Both these devices are used in various industries such as photography or astronomy etc.

Difference between Mirror and Lens

The core differences between the mirror and lens would be due to their construction and working. The mirror is the apparatus which reflects the light falling on them. Whereas, lenses are the ones that manipulate light. The mirror is having one side of reflective coating. Lenses are classified into various types: simple lenses and compound lenses, and depending on the type of refraction image formed by lenses: concave and convex lenses.

Mirrors have no focal point (plane mirrors) or only one focal point (spherical mirrors) Lenses have two focal points.
