Definition of 'reflector' Definition of 'reflector'. reflector (rɪflektəʳ ) A reflector is a small piece of specially patterned glass or plastic which is fitted to the back of a bicycle or car or to a post beside the road, and which glows when light shines on it. A reflector is a type of telescope which uses a mirror that is shaped like a ball.

Definition of a Projector Definition of a Projector. A projector is a device that uses light and lenses to take an image and project a magnified image onto a larger screen or wall. Projectors can magnify still or moving images depending on how they are built. The image must be shone through a sealed tube or frame when passing through the lenses to maintain focus.

Board Reflectors The Gold Reflector gives a hard light source similar to the silver AND it will change the color temperature of the light. The Gold reflector is probably best used to liven up skin tones and boost eye light, especially for photo shoots at the beach or in the waning sunlight of late afternoon (before golden hour).

- (těl'ĭ-skōp') 1  An arrangement of lenses, mirrors, or both that collects visible light, allowing direct observation or photographic recording of distant objects. ◇ A refracting telescope uses lenses to focus light to produce a magnified image.

Reflective practice For example 'the reflector' refers to a person who uses reflection of some sort. A 'critical reflector' more specifically refers to someone who uses Reflective Practice as a learning tool to question and evaluate themselves, others and situations. A 'non-reflector' is a person who rarely or never uses reflection.

Reflection (physics) Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.

- In optical astronomy there are three basic types of telescopes; the refractor, the catadioptric and the reflector. The refractor telescope receives light through the objective lens (the large lens closest to the subject being viewed) and sends it to the eyepiece for magnification.

Parabolic aluminized reflector light 20 PAR cans. A parabolic aluminized reflector lamp (also PARCAN light, PARcan, or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. Usage includes locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights (cans in the United States).

Reflecting telescope A reflecting telescope is a telescope that uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century,by Isaac Newton, as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telesco

refracting telescope Most large optical telescopes are reflecting telescopes because very large mirrors, which are necessary to maximize the amount of light received by the telescope, are easier to build than very large lenses. Any of various devices, such as a radio telescope, used to detect and observe distant objects by collecting radiation other than visible light.

Focuser Focuser. A focuser is part of the telescope mechanism which allows the telescope to adjust its focus, done by either turning a knob or gear in the telescope; thereby adjusting its eyepiece or mirror. There are many different types of focusers, varying in design, use, and models.

reflection The turning back of a wave, such as a light or sound wave, when it encounters a boundary. Reflected waves return immediately to their original medium instead of entering the medium they encounter. ♦ According to the law of reflection, the angle of reflection of a reflected wave is equal to its angle of incidence.

Definition: Absorption of light; Absorb; Absorbing surface; Black card Absorption of light; Absorb; Absorbing surface. The absorption of light occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material. The transfer creates heat (usually small amounts). An absorbing surface prevents reflection or diffusion of light striking on the surface. In practice, perfect absorption does not exist.

marketing Marketing differs from selling because (in the words of Harvard Business School's retired professor of marketing Theodore C. Levitt) Selling concerns itself with the tricks and techniques of getting people to exchange their cash for your product. It is not concerned with the values that the exchange is all about.

- Impact Theory Currently the leading theory for the origin of the Moon involves a collision with Earth by an object slightly larger than Mars. If such an object struck at a glancing blow, most of it and some of the Earth would have rose up as a cloud of material to above 22,000 kilometers (13,700 miles), and condensed into particles that orbited the Earth.

Reflecting Telescope Facts Reflecting Telescope Facts. A reflecting telescope is one that causes an image to reflect at a focus point by using mirrors. It was invented during the 1680s by Isaac Newton. These telescopes improved the before used refracting telescopes by giving a clearer picture.eflecting telescopes are also called reflectors. Most telescopes used by astronomers today are reflectors. In Newtonian telescopes, one mirror is used to capture the image while another mirror is used to reflect the image from the first mirror.

Difference Between Refractor and Reflector Telescopes Refractor vs Reflector Telescopes | Refraction vs Reflection Telescopes. Reflector and refractor are basically the main two types of telescopes mostly used in astronomy. They are also known as reflection telescopes and refraction telescopes. These are mainly optical devices, which use visible light to produce images of distant objects, such as planets, stars, nebulae and galaxies.
