['Plane Mirror — These are flat mirrors that reflect images in their normal proportions, reversed from left to right. ... ', 'Concave Mirror — Concave mirrors are spherical mirrors that curve inward like a spoon. ... ', 'Convex Mirror — Convex mirrors are also spherical mirrors.']

The modern mirror is made by silvering, or spraying a thin layer of silver or aluminum onto the back of a sheet of glass. Justus Von Leibig invented the process in 1835, but most mirrors are made today by heating aluminum in a vacuum, which then bonds to the cooler glass [source: Britannica].

There are five major types of gradients: Linear, Radial, Angle, Reflected and Diamond. In addition you can vary the colours within the gradient, the opacity and make use of 28 modes which include: Diffusion, Multiply, Screen, Color Burn, etc.

There are two main types of optical telescope - reflectors and refractors. Reflectors use a mirror to collect the light, whilst refractors use a lens. ... Catadioptrics are short, wide telescopes that use both mirrors and lenses. Large lenses suffer sag under their own weight.

Spherical Mirrors. ... A convex mirror is a spherical mirror where the mirrored surface is on the outside of the spherical curve. And a concave mirror is a spherical mirror where the mirrored surface is on the inside of the spherical curve. Plane mirrors produce virtual, upright images that are the same size as the object.

The focal length of a mirror is given by f2​=v1​−u1​.

Most common household mirrors are "back-silvered" or "second-surface", meaning that the light reaches the reflective layer after passing through the glass. A protective layer of paint is usually applied to protect the back side of the reflective surface . ... Front-coated mirrors achieve reflectivities of 90–95% when new.

A specular reflection is what you get from a polished surface, or mirror. It is clear, and you can see "through" the mirror. A diffuse reflection is what you get from a white wall. The light is bounced of it, but in random directions so you cannot see the light source in the reflection.

The focal length of a plane mirror is infinite. When parallel rays fall on a mirror surface, they are brought to a point after reflection.

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.

Two-way mirror. Also known as two-way glass, a two-way mirror is glass that is reflective on one side and clear on the other, giving the appearance of a mirror to those who see the reflection but allowing people on the clear side to see through, as if at a window.

The focal length of a concave mirror is negative and that of a convex mirror is positive. You can also prove the same by using the mirror formula (1/f = 1/v +1/u). Let's see how, Since we know object is always placed on the left side or direction opposite to the incidence ray of the mirror.

Mirrors help reflect light and make a room feel larger at the same time. In rooms with little sunlight, add a large mirror on the wall above a fireplace, over a sofa or behind a bed to make the room feel lighter. The reflectivity of mirrors makes them a perfect decorating tool when sunlight is at a minimum.

Check these three factors when looking for a high quality mirror: glass quality, mirror thickness, and mirror silvering. In glass quality, see if the glass used in the mirror has no inconsistencies in its makeup and does not distort a reflection. ... Quality mirrors have a high quality, thick coating of silvering.

Mirrors don't cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be used to attach to the mount. Reflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned.

A combination of concave and convex mirrors and lenses is used to collect a larger area of light and focus it onto a smaller, possibly brighter image surface. Concave mirrors in particular would be used in the collection and focus of the initial light received.

The word "mirrorless" indicates that the camera does not have a reflex mirror or optical viewfinder like a conventional digital single-lens reflex camera (DSLR), but an electronic viewfinder which displays what the camera image sensor sees. Many mirrorless cameras retain a mechanical shutter.
