They would be felt as heat, such as the warmth radiated
by a fireplace, or by the sun on a clear day.
infrared
infrared waves and infrared radiation both are same
The term "infrared" refers to electromagnetic waves, not to sound waves.
Infrared waves. Infrared waves are also used in retina scans.
No, infrared is a type of electromagnetic waves, and those are transverse waves.
Waves with lower frequency: for example radio waves.
No. Infrared is a type of electromagnetic waves, and therefore, a transverse wave.
They most use infa red but they use wireless for the more recent technology.
No; sound is a mechanical wave, infrared is a part of the electromagnetic spectrum.
Infrared radiation is a form of energy with wavelengths that are longer than red light. You can look up pictures of a Light Waves Spectrum to find out the length of red light. infrared radiation is invisible, but can be felt as heat.
the electromagnetic spectrum (all existing radiation) is organized in order of shortest wavelength from the left to longest wavelength from the right. Infrared waves, felt as heat, are slightly longer than the visible light spectrum, and microwaves longer still, and radio waves longer still.
Ultraviolet is higher frequency, then visible light, then infrared.
