conduction
Electricity to heat, then black body radiation (i.e. heat to light [e-m radiation]).
Radiation
Much of the radiation created by a heat lamp is infrared electromagnetic radiation. A heat lamp is generally designed not to emit too much visible light, but is set up to emit most of its radiation in the red and "below red" (infrared) areas of the spectrum.
for example a lamp is turned on and then it gets hot after a while as the electricity has caused it get hot and turn to heat energy or has conducted the heat
Thermal Radiation.Radiation.There are three main types of heat transfer methods in Thermodynamics. Radiation, Convection, and Conduction. Food warmed by infrared light is heat transfer by radiation. What you feel coming from the infrared lamp is radiant heatenergy.
conduction
Generally, electromagnetic radiation: ie. heat and light.
Yes
Electricity to heat, then black body radiation (i.e. heat to light [e-m radiation]).
A heat lamp emits infrared radiation, which is a type of electromagnetic wave. Infrared radiation has longer wavelengths than visible light, and it is often used to provide heat in various applications such as in heat lamps or infrared saunas.
Radiation
convection
Electromagnetic radiation travelling through space (the air).
electromagnetic waves will transfer thermal energy from the lamp to the fries
