Heat haze, also called heat shimmer, refers to the inferior mirage observed when viewing objects through a mass of heated air. Common instances when heat haze occurs include images of objects viewed across asphalt concrete (also known as tarmac ), roads and over masonry rooftops on hot days, above and behind fire (as in burning candles , patio ...
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

Heat lightning (not to be confused with dry thunderstorms, which are also often called dry lightning) is a misnomer [1] used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have accompanying sounds of thunder.
The heat deflection temperature or heat distortion temperature (HDT, HDTUL, or DTUL) is the temperature at which a polymer or plastic sample deforms under a specified load. [1] This property of a given plastic material is applied in many aspects of product design, engineering and manufacture of products using thermoplastic components.
Many heat lamps include a red filter to minimize the amount of visible light emitted. Heat lamps often include an internal reflector. Heat lamps are commonly used in shower and bathrooms to warm bathers and in food-preparation areas of restaurants to keep food warm before serving. They are also commonly used for animal husbandry. Lights used ...
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
An American style clothes dryer with a rear control panel A European style clothes dryer with a front control panel. A clothes dryer (tumble dryer, drying machine, or simply dryer) is a powered household appliance that is used to remove moisture from a load of clothing, bedding and other textiles, usually after they are washed in the washing machine.
Dryer was a filmmaker in the early 1970s. On one project, he worked with Dr. Elsa Garmire, a California Institute of Technology physicist interested in laser light art. . (She had previously worked with other artists on special event laser shows.) [1] Dryer was disappointed because the resulting film, LaserImage, [2] did not have the pure color and shimmer of laser l
