== == Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.

What are infrared lights use for?
There are a lot of things that infrared lights are used for, primarily sight enhacements. Just to name a few, infrared lights are used for night vision, thermography, hyperspectral imagery, tracking, and heating.
Can dogs see infrared lights?
No, dogs cannot see infrared lights. They can see some colors, but their vision is limited compared to humans.
What are examples of invisible lights?
X-ray & infrared
How do astronomers use infrared lights?
Astronomers use infrared light to map the dust in between stars.
What types of lights are used in motion detection?
Common types of lights used in motion detection systems include infrared lights, ultrasonic lights, and microwave lights. These lights emit different types of signals that are reflected back when motion is detected, triggering the detection system to activate lighting.
Do plants grow better under infrared lights?
No, since there is insufficient energy in infrared photons to carry on photosynthesis.
Are infrared lights safe for use in home therapy devices?
Yes, infrared lights are generally considered safe for use in home therapy devices when used according to manufacturer instructions.
In which ways can infrared lights be used?
Infrared lights can be used in many different ways. The common ways it is used are to detect the changes in temperature, to measure the heat radiated by an object and it can also be used in cooking.
How do Motion Sensing Lights Work?
Motion sensing lights use a passive system that detects infrared energy. These sensors are known as PIR (passive infrared) detectors or pyroelectric sensors. Human skin averages to be 93 degrees F, which radiates infrared energy in a wavelength that is between 9 and 10 micrometers. The sensors dectect quick movement of objects that radiate between 8 to 12 micrometers of infrared energy.
What is significant about an IR laser?
Infrared lasers are dangerous to the human eye, because it is extremely bright. Infrared lights are invisible and keeps the body from using it's "blink reflex".
Which fish has capability to see both infrared and UV lights?
bees and butterflies can see ultra violet
What is the difference between ultraviolet and infrared lights?
Wavelength, frequency, and energy carried by each photon (light quantum).
