The lower frequency boundary is open to discussion; it is difficult to know where the far infrared becomes the "millimetric" microwaves. Somewhere round about 10THz (=1013Hz) The upper bound is easy - if it is just too low a frequency to see, then it is infrared. 384THz (=3.84 X 1014Hz)
Less than the frequency of visible light. About 430 to 1 THz.
300 thousand kilometers (186,000 miles) per second in vacuum.
Heat waves (infared) and sound waves.
Not really dangerous . . . .
Ultraviolet rays or infared rays
infared rays - 92 % positive
infared light waves
ay gagu
inferd is its own wave it doesnt emit a wave
radio waves, microwaves, infared, visible light, UV light, x rays, gamma rays
radio waves, microwaves, infared, visible light, UV light, x rays, gamma rays
I believe they would be infared, radio, ultraviolet, and electromagnetic waves.
REMOTES used to control Televisions & Night Vision Camerasmake use of INFRARED light waves.
No doubt about it; infra red rays are transverse in nature. Only sound waves are longitudinal. Electromagnetic waves are transverse waves. Infra red belongs to that family of electromagnetic waves.
