Does infrared have high or low frequency?
Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz.
What has a lower frequency than infrared light?
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
How many Hertz are infrared waves?
Regions of the Electromagnetic Spectrum
|Wavelength (m)||Frequency (Hz)|
|Microwave||1 x 10-3 – 1 x 10-1||3 x 109 – 3 x 1011|
|Infrared||7 x 10-7 – 1 x 10-3||3 x 1011 – 4 x 1014|
|Optical||4 x 10-7 – 7 x 10-7||4 x 1014 – 7.5 x 1014|
|UV||1 x 10-8 – 4 x 10-7||7.5 x 1014 – 3 x 1016|
What is the frequency range of infrared?
300 GHz to 400 THz
Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.
Which has more energy radio TV or infrared?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
Are infrared waves harmful?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
