5.Physics about Infrared heating

A halogen heater is used for radiant heating of near infrared rays. Of the electromagnetic waves radiated from a heating element at about 3000℃, the maximum wavelength is about 1μm in the near infrared region. A convex parabola is drawn ...

An object with an absolute temperature of 0K (Kelvin) or higher radiates a wavelength corresponding to the temperature of the object as an electromagnetic wave. The object that received this electromagnetic wave has received heat. This transfer of heat is ...

There are two main types of reflection. Regular reflection Regular reflection refers to reflection that holds the “law of reflection” in which the angle of incidence and the angle of reflection of light incident from a light source are equal. ...

Every substance is made up of very small particles. The molecules that make up that substance have different molecular motions depending on the temperature. A molecule is made up of several atoms linked by chemical bonds, and any bond. Each ...
