A mirror is a device that is based on the principle of reflection whereas lenses are devices that are based on the principle of refraction. They are both used in fields such as optics, astronomy, Photography and various other fields.

How do you replace indicator lens on a Volkswagen Passat 1.9TDI?
hi thereprise the mirror glass out and remove the outer casing and also remove the backing, there are 2 small screws at the bottom of the mirror remove them and replace the lens, dont worrie about which way you connect the mirror glass electrics as it is a curcuit,good luck
2 What type of lens does a drop of water behave like?
A drop of water behaves like a convex lens, which causes light passing through it to converge and form an image. This bending of light is due to the differences in refractive indices between the air and water.
How do you find the refractive index of a liquid by using a convex lens and a plan mirror?
Using Snell's law, n(1)=(n(2) x sin angle (2)) / sin angle (1).n(1)= The refractive index of the more optically dense medium.n(2)= The refractive index of the less optically dense medium.angle (1)= The critical angle of the two mediums.angle (2)= 90 degrees since when light is at the critical angle it undergoes total internal reflection.Since sin 90= 1, this can be ignored, resulting in n(1)= n(2) / sin angle (1)
What is the Pano mirror lens?
The Pano mirror lens is a great tool for taking 360° panoramic photos with the minimum of fuss: 1- Mount the Pano Pro unit and your camera onto your tripod, pointing vertically upwards, using the supplied quick-release adapter kit. 2- Focus the camera on the mirror and take one shot. 3-Use the FREE software to process your image into a 360° panorama.
What if there was 2 identical earths?
There would be an impenetrable mirror in between.
What does the curved mirror on a telescope do?
The mirror in a telescope is a concave mirror. That shape redirects all the light coming from a distant object that hits the mirror into a focusing lens. The mirror may be as small as several inches or many feet in diameter and it concentrates the light so it can be focused by a small eyepiece that may be only a fraction of an inch in diameter. The mirror serves the same purpose as a large lens in a refractive telescope. It takes a large cross section of light and focuses it into the eyepiece of the telescope but it does it by reflection rather than refraction. The reflective mirror is preferred over a lens for several reasons. The light reflected by a good quality silvered mirror loses very little of its intensity. Light passing through a lens loses intensity each time it passes through a glass surface and it must pass through 2 surfaces of a lens. The mirror bends the light one time and a lens bends it twice. The more times you bend light, the more chance you have to introduce distortion because of imperfections of the surface. If the glass of a lens is not ultra pure and without imperfection, the light is further distorted. The quality of glass in a mirror does not affect the light because the light does not pass through the mirror because the light is reflected off the first surface. When very large telescopes are involved, a refraction lens would weigh many times what the reflective mirror weighs.
What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
What is the difference between a simple and compound microscopre?
simple microscope only have 1 lens and compound microscope uses 2 lens \
What are the key differences between the Fuji X100T and XT2 cameras, and which one would be a better choice for my photography needs?
The key differences between the Fuji X100T and XT2 cameras are that the X100T is a fixed-lens compact camera with a 23mm f/2 lens, while the XT2 is a mirrorless camera with interchangeable lenses. The XT2 offers more advanced features and better performance, making it a better choice for photography enthusiasts who want versatility and higher image quality.
Does a compound microscope have one lens?
A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
