Tests have shown that both visible Red Light Therapy and Infrared light affect at least 24 different positive changes at a cellular level. Visible Red light, at wavelengths from 630-660nm (nano meters) and Infrared light at 880nm penetrates tissue and is very beneficial in treating problems of the skin such as fine lines, wrinkles, and crow's-feet.

Infrared light is a type of electromagnetic radiation that has longer wavelengths than visible light. It is commonly used in remote controls, thermal imaging, and some forms of communication. Infrared light is not visible to the human eye but can be detected by specialized cameras and sensors.

Do flies see in infra red?
Flies do not see in infrared. They have compound eyes that are sensitive to different wavelengths of light, but they primarily rely on visible light for their vision.
What has a longer wave length a infrared radiation or red light?
Infrared radiation has a longer wavelength than red light.
Does a light bulb convert electrical energy to both heat and light energy?
Yes. Heat is radiated as infra-red, a longer wavelength than visible light, but otherwise similar. Incandescent light bulbs with a heated filament emit infra-red light as heat, and only a small part of the emission is visible. Other light bulbs using electrical discharges in neon gas (known as fluorescent bulbs) do not produce as much infra-red, and are more efficient in the conversion of electrical energy into light. If you feel a fluorescent tube you will find it is only warm, but DO NOT feel an incandescent bulb or you will burn your hand, its so hot.
Does infra red light cast a shadow?
No, infrared light does not create a shadow because it is not visible to the human eye. Shadows are formed when light is blocked by an object, and since infrared light is not within the visible spectrum, it does not produce shadows as we perceive them.
Is the wave length of infrared light too short to be seen or too long?
The wavelength of infrared light is too long to be seen by the human eye. Our eyes are sensitive to visible light, which has shorter wavelengths than infrared light.
Does ultraviolet light have a lower frequency than visible light?
No, ultraviolet light has a higher frequency than visible light. Visible light has wavelengths between about 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.
Who invented infrared night light?
Infrared night lights have been around for a while and the specific inventor is not readily available. Infrared technology has been used for various applications including night lights to provide low-level lighting without disturbing sleep.
What part of light is heat?
Infra red part of light is responsible for heat.
Would radioactive isotopes be seen as infra red light?
no
What band of light is below the visibile spectrum?
Infra Red
Why do you see a white spot on the camera-display when you make a photo of a remote-control?
Because remote controls use infra red light to communicate with the TV, stereo or what ever the remote is for. Infra red is a type of light we cannot see with our eyes, but cameras and video cameras turn infra red into visible light.
What wavelength does white light from the sun have?
White light from the sun contains a broad spectrum of wavelengths ranging from about 400 nm (violet/blue) to 700 nm (red), covering the visible light spectrum.
What animal can see uv rays and infra-red light?
Goldfish
What are the em waves that are just below visible light?
Infra red.
What kinds of photography depend upon infrared light?
If you actually mean infra-red light, it is simply infra-red photography. Color and b&w infra-red film as well as filters for electronic flash may still be available from specialty suppliers. If you are referring to images created by recording heat energy emissions, it is not really infra-red photography. That is correctly referred to as thermography.
What is the danger of infrared light?
Infra-red light is heat, so if you have a lot of it, you will suffer from burns...
How is heat tranferred by radiation?
First of all it is important to note that heat and infra-red rays are NOT the same thing. When an object gets really hot it starts to glow, emitting red light at first, (hence the phrase: 'red hot') because red is the least frequency. Hotter objects emit light of higher frequency. A light bulb and the Sun are both examples of this. But infra-red rays are even lower in frequency than red light. Infra-red rays are emitted in the same way by objects at room temperature. That means you, your computer and everything around you are 'glowing' with this infra-red radiation. Infra-red rays carry energy between objects at the speed of light. This process causes relatively hot objects to cool down faster.
