Difference Between Mirror and Lens

Main Difference

Lens and mirrors are widely used terms in optical physics, moreover, they have a wide range of application in daily life as well, they both are usually misunderstood in terms of their functionality and performance. They both have a large number of differences from each other though they have some similarities as well. Lens, as well as mirror, is the two various tools which are usually utilized and employed inside optics. A mirror is actually a gadget which is in accordance with the basic fundamental rule of the reflection whereas, in contrast to lenses are generally products which happen to be dependent upon the basic principle associated with refraction. These two products are extremely important within areas, for example, optics, astronomy, digital photography as well as other fields. A lens can be described as a crystal-clear unit along with a couple of spherically curved surfaces, generally made from glass or even with plastic, which utilizes refraction in order to create a picture associated with an object. Mirrors, which happen to have spherical surfaces made to reflect rays, additionally from illustrations or photos. A method associated with lenses or mirrors creates a perception by means of accumulating rays through an item after which you can bring about those to converge or even diverge. The positioning in which the particular rays meet to or even diverge as a result of would be the image. A genuine image is actually created in the event the optical system brings about the particular rays to converge to a degree, some sort of virtual picture is actually created along at the location from where they appear to be able to begin.

What is Mirror?

A mirror is definitely a good product which displays light in such a manner in which, with regard to incident light in the certain selection of wavelengths, the particular reflected light maintains numerous or even the majority of the comprehensive physical attributes from the unique light. This is certainly completely different from various other light-reflecting objects that do not effectively keep the majority of the actual wave signal besides color as well as diffuse reflected light. Probably the most acquainted kind of mirror would be the plane mirror, that features a smooth display surface area. Curved mirrors can also be utilized, to create and generate amplified as well as lessened illustrations or photos or even concentrate light or merely distort the mirrored picture. Mirrors are generally employed for personalized self-care or even appreciating yourself, ornamentation, and also architectural mastery. Mirrors may also be employed in a technological piece of equipment, for example, telescopes as well as laser devices, digital cameras, in addition to commercial machinery. The majority of mirrors are equipped with visible light; nevertheless, mirrors manufactured for various other wavelengths associated with electromagnetic radiation are usually employed. Concave, as well as converging mirrors, bend back to the inside just like a spoon.This provides these types of mirrors the opportunity to produce a perception or image whenever their particular curvature bounces light to some particular region when in front of them. This particular region is referred to as the focus or the focal point. As a result of a long way away, objects will certainly appear inverted, but because you receive more detailed as well as pass the focal point, the whole picture flips as well as magnifies. Concave mirrors are widely-used inside everything right from shaving mirrors to illumination to the particular Olympic torch. basically, the mirror has the two types concave or converging but when we see mirrors in the detail we find many types of the mirrors for example non-reversing mirrors , Acoustic mirrors, plane mirrors , silver mirrors and two-way mirrors.

What is Lens?

A lens can be described as a transmissive visual unit which usually has an effect on the main focus associated with a light ray by means of refraction. A straightforward lens is made up of a single section of materials, despite the fact that a compound lens is made up of a number of simple lenses (substances), generally alongside perhaps the most common axis. Lenses are manufactured from crystal-clear elements, for example, glass, ground as well as refined to some preferred shape. A lens can easily concentrate light in order to create a perception, as opposed to a prism, which usually refracts light without having focused. Devices which usually, in the same manner, refract radiation apart from obvious light can also be called lenses, including microwave contact lenses or perhaps traditional acoustic lenses. Even though it may be possible to purchase lenses which may have spherically bent surfaces, almost all lenses possess spherically bent surfaces. The majority of optical systems make use of rounded lenses simply because they’re much easier to create as well as less expensive to acquire when compared with aspherical lenses. Lens developers establish the particular curvatures, the particular thicknesses, as well as the refractive indices belonging to the lenses to manipulate the manner in which lenses graphic items.

Key Differences

  1. The working principle of the mirror is based on the principle of the reflection whereas lenses are based on the concepts of the refraction
  2. Light is reflected from the mirror whereas on the other hand, contrary to the mirror, light enters into the lens, it is refracted by the lens
  3. Lenses have two focal points, on each side of the lens but it is not the case in the mirrors
  4. A concave mirror converges light towards a focal point. With regard to lenses, light converges to some extent for any convex lens it should be kept in mind that, a convex mirror diverges light, similarly like a concave lens.
  5. Ray diagrams are different for both lenses and mirrors
  6. Mirrors have many types but lenses possess five to six types.
  7. Besides glass and plastic, other materials could also be used and employed in the formation of the mirror whereas lenses only require glass or plastic
  8. A true mirror perfectly reflects light from its silvered surface whereas on the other hand a perfect lens truly refracts light which passes through it.
