- Infrared heating primarily utilizes infrared radiation to heat surfaces. Infrared radiation is a form of electromagnetic radiation with wavelengths longer than those of visible light.
- It is capable of transferring heat directly to objects and surfaces without significantly heating the surrounding air.
- This property makes infrared heating suitable for various applications, such as heating indoor spaces, industrial processes, and even certain medical treatments.
- The other options (X-rays, microwave radiation, and ultraviolet radiation) have different wavelengths and are not commonly used for surface heating in the same way as infrared radiation.
