If heat is infrared radiation, are light and heat same?

The optical radiation consists of three kind of radiation,first is ultraviolet,second is visible light and third is infrared radiation.The infrared radiation is major carrier of heat energy and yes visible light can also produce heat.But it depends upon absorbance material. read more

Because most heat generates light in the infrared, scientists often refer to infrared light as heat. This is a generalized term or a convention. Technically heat energy and light are different things, but heat energy can be measured by its EM radiation. read more

The energy of electromagnetic radiation (particularly a photon) is. E = h ν = h c λ . where h is Planck's constant, ν is the frequency, c is the speed of light, and λ is the wavelength. So you can see that as wavelength increases, the energy goes down. read more
