Mell Which uses a lens and two mirrors?
Answer Expert Verified. Out of the choices given, the one that uses a lens and two mirrors is a reflecting telescope.
How are mirrors and lenses used?
A lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object. Mirrors, which have curved surfaces designed to reflect rays, also form images. Positive and negative lenses can both form real and virtual images. …
What objects use lenses?
Common optical devices that use lenses include eyeglasses, contact lenses, magnifying glasses, cameras, projectors, telescopes, binoculars, and microscopes.
How mirrors and lenses are used in telescope?
Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics. That light is what we see when we look into the telescope.
How important are mirrors and lenses in our daily life?
In all, mirrors are useful in everyday life. Lenses, however, are essential to our lives. In fact, all the optical devices that are part of your everyday life— eyeglasses, contact lenses, magnifying glasses, microscopes, cam- eras, camcorders—produce images following the same laws of reflection and refraction.
How do we use mirrors in everyday life?
Mirrors serve many functions for us: letting us see ourselves when we put on makeup, wash our faces, try on clothes and more. This is also true for much of the animal kingdom; as peacocks, apes and elephants like to admire their own reflection too. When I brush my teeth, I can see exactly where I need to reach.

When we are in face-to-face interactions, we get feedback on what they are experiencing internally from others’ reactions to us.
What is the difference between a mirror and a lens?
Mirror are having one side reflective coating and on the other hand, lenses are classified into various types simple lenses and compound lenses and the image formed by lenses: concave and convex lense depends on the type of refraction happening.
What kind of mirror has a concave lens?
Light falling on such a mirror converges at a point and reflects back from the surface of the concave mirror, therefore such mirrors are also called converging mirrors. An image formed by the concave lens can be real and inverted as well as virtual and erect.
Is it possible to hand hold a mirror lens?
The small physical size and weight of the Mirror lens means that it is possible to hand hold with an appropriately fast shutter speed and of course the lens does not look like a paparazzi tool, so it is discrete.
What are different types of mirrors and their uses?
Listed below are some types of mirrors and their uses which can help you to make the right choice. Plane mirrors: These types of mirrors have a planar or a flat surface. The image formed is almost of the same size of the specific object. At one time these plane mirrors were flat pieces of any precious metal or copper or brass.
