Infrared heater - Wikipedia

An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from 780 nm to 1 mm. No contact or medium between the two bodies is needed for the energy transfer.

Which Radiation Interface Should I Use for My Heat

Mar 04, 2021 · Radiation does not need any matter to be transferred from one object to another, but the interaction with matter turns the electromagnetic wave into heat. From its almost unhindered way from the Sun to the Earth, the action takes place as the radiation enters Earths atmosphere, where the high number of molecules absorbs and scatters the

Microwave oven - Wikipedia

A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the

Lighting - Wikipedia

Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.
