Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
