Why convex mirror is preferred as driver's mirror?
convex mirrors are preferred as drivers mirror because they reflect more area than plain or concave mirror.
Why are concave mirrors used in flashlights and automobile headlights?
because the reflected light would spread out over a wide area if convex mirrors were used, whereas concave mirrors focus these reflected light rays into a beam, which give flash lights and headlights their unique characteristic.
Why the street light refelector are convex in nature?
this is because convex surfaces , being curved outside, have a wider field area. Car rear view mirrors are also a good example of this. In these, convex mirrors are used. This is because, convex mirrors, being curved outside, have a wider field area and show the image of a larger area
Do telescopes use a reflecting mirror to focus light onto a small area?
Many telescopes do, especially the largest ones.Others use a refracting lens to do that job.(Note: Our entire discussion so far has included a redundant amountof redundancy. All mirrors reflect, and alllenses refract.)
Does a rough surface reflect light in many directions?
Highly polished, shiny surfaces reflect light the best as they are REFLECTive. White or bright surfaces also reflect light well. Dull, Matt surfaces are the worst reflecters of light
How is a shadow formed explain?
A shadow is made when an object blocks out light coming from a light source. because there is less light particles in that area, surfaces don't reflect as much, making it darker in that area. that is why you can't see when there is no light source.
Why are concave mirrors used in headlights of cars?
Car headlamps use parabolic mirrors to concentrate and focus the light in one direction. Without these mirrors, one would either waste the undirected light or the light would shine in all directions, which would blind the driver.
Does your shadow have color?
No. Color is the reflection of light and shadows are areas where light does not reflect off of an object. The dark area you see is the area where light, and there for color, is not present. Simply stated, a shadow does not have color. On a side note: black is not a color, it is the absence of color.

Does the use of mirrors increase light?
Sort of. The concave mirror will collect all the light of a larger area, and concentrate it into a small spot. This will not change the colour temperature of the light, but will increase the watts per square centimetre at the focus.
What kind of curved mirror do you see in most of the department stores why do they use this kind of mirror?
Convex circular mirrors, mounted high. These are used for security purposes because they reflect a very wide angel of area.
Why are reflectors and mirrors used in solar cookers?
Mirrors are used to focus the heat on a central area where the food is.
