- Electromagnetic energy usually defined as heat in the invisible part of the
- A portion of the electromagnetic spectrum to which the human eye is not sensitive but which can be used with infrared film and filter to record images of unusual tonal balance. infrared rays produce heat when they strike objects. see: heat filter.
- Electromagnetic radiation with wavelengths longer than visible light, but shorter than microwave radiation.
- That region of the electromagnetic spectrum at wavelengths immediately above the visible spectrum; the heat in this region of the spectrum which is generated by a light source usually is undesirable (since it represents a loss in efficiency), but such heat is used in industrial applications for drying, baking a surface, etc.
