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.
What else can I help you with?
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 lower frequency and longer wavelength than red light. Note that "infra" means "below" in this case referring to the lower frequency.
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 infra-red light is LONGER than the wavelength of red light, and longer than anything to which the eye responds.
What part of light is heat?
Infra red part of light is responsible for heat.
What band of light is below the visibile spectrum?
Infra Red
Would radioactive isotopes be seen as infra red light?
no
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 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...
What colour of light will be absorbed first as the sunlight enters water?
Infra-red
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.
Will a remote control work through a drywall?
A TV remote? Probably not. TV remotes work via infra-red light. When you press a button, the command is sent to the TV through the infra-red light on the remote, which is picked up by an infra-red receiver on the front of the TV. Light cannot travel through walls. Infra-red extender systems are available to allow a remote in one room to operate equipment in another and can be purchased at AV dealers or on line. If you mean a remote for a racing car or something, then yes, because these work by radio waves, not infra-red light, which can pass through most walls, depending on the strength of the waves.
Radiation with a wavelength slightly longer than visible light is called?
Infra-red.
