Why you use mirrors as reflectors and not alluminium?
Shrutikadutta
Nearly all modern mirrors are aluminum. An aluminum coating is placed on a sheet of polished glass. In common mirrors we observe this aluminum reflector through the glass layer. But if we turn the mirror around, we can bounce light directly off the aluminum, and this is called a "front surface mirror." (Common mirrors have a coating of hard paint over the thin delicate aluminum coating to prevent scratches.) It's perfectly possible to form a mirror by grinding and polishing a thick aluminum slab. But aluminum is softer than glass, and would collect scratches and dings. Also, aluminum is expensive, so an aluminum mirror costing several dollars might replace a glass mirror costing a few cents.

What type telescopes use mirrors to bring light to focus.?
Reflectors - the main two types being Newtonian and Cassegrainian.
What type of telescope concave mirrors to gather light and view the image?
Reflecting telescope. Most useful reflectors are compound types, combining a system of mirrors and lenses, such as the Newtonian and Cassegrain.
What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
What is difference between emissivity and reflectance?
Reflectors just reflect the light absorbers actually absorb it.
What telescope collects light with a mirror?
The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
What are 2 types of telescopes?
Refractors (with lenses)Reflectors (with mirrors)
Why are reflectors and mirrors used in solar cookers?
Mirrors are used to focus the heat on a central area where the food is.
What is one rfeal life example for reflectors?
mirrors=reflects light
Where is a concave mirror used?
concave mirrors are used as rear view mirrors and serve dentists and used as reflectors
What type telescopes use mirrors to bring light to focus.?

Who is Peterson Manufacturing?
Peterson Manufacturing--a leading manufacturer of vehicle lights, reflectors, and mirrors for the automotive and trucking industry
What telescope uses mirrors to bounce light toward the eyepiece?
Reflecting telescopes do this. There are many different kinds of reflectors.
What type of telescope concave mirrors to gather light and view the image?

What are good reflectors of sound with example?
the moon , frosted glass, aluminium
Why are concave mirrors used in reflectors and projectors?
Concave mirrors project a beam of light outward, which is what you want in a reflector or projector. This is also why they are used in vehicle headlight casing. It projects the beam of light further down the road so you can see better.
Why are convex mirrors used as reflectors?
convex mirror can form image of object speared over a large area . so these helps the drivers to see the traffic behind them.
