Electromagnetic (EM) radiation is the word we use for any sort of energy wave that propagates through space. We can measure the frequency of the wave, or the wavelength.

The speed of light is 186,000 miles per second, which is about 300,000,000 meters per second. We can use this to convert frequency to wavelength; the frequency (in Hertz) times the wavelength (in meters) equals the speed of light.

The EM spectrum includes radio, microwaves, heat, light, X-rays and gamma rays; it is all electromagnetic radiation, and the only difference is the frequency (or wavelength). So heat rays are part of the EM spectrum that is just below the red color of light, so "infra-" (below) red; infrared. Infrared (IR) is light that is a frequency a little below what our eyes can see, just as ultraviolet (UV) rays are just light that's a little higher in frequency than our eyes see.

We see when light is reflected back to our eyes. When light hits vegetation, it reflects best in the IR range, so satellite photos in the IR range can see tiny changes in the way we see plants.

Their wavelength.


What is one difference between visible and non-visible light?

One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.


What kind of electromagnetic radiation did the IRAS satellite detect?

visible light, infrared rays, and microwaves


Which form of radiation has the longest wavelength between infrared and visible?

Infrared radiation has longer wavelengths than visible light.


What is difference between visible and infrared light?

Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.


What is the difference between Ultravlotet and infrared?

They are the extreme ends of the spectrum. The ultraviolet has much more energy than the quantum of the infrared wave. They are quite the opposite of each other. Consider the visible spectrum of VIBGYOR. Ultra violet occurs on the left of V and infrared occurs on the right of R. Hope you understand the difference. They are the extreme opposite poles beyond the visible spectrum.


What electromagnetic wave is located between infrared radiation and ultraviolet radiation in the visible spectrum?

The term "electromagnetic" is the wrong term. The correct term is "photoelectric". Aslo the phrase between the infrared and ultraviolet should be stated: between the thresholds of infrared and ultra-violet light. So the correct question would be: What is the region of the photoelectric spectrum that lies between the thresholds of infrared and ultra-violet light? Answer: The visible light spectrum


What property spells difference between infra red and ultra violet radiation?

One key difference between infrared and ultraviolet radiation is their wavelengths. Infrared radiation has longer wavelengths than visible light, while ultraviolet radiation has shorter wavelengths. Additionally, ultraviolet radiation is more energetic than infrared radiation.


What is the difference between thermal imaging and infrared imaging?

Thermal imaging and infrared imaging are often used interchangeably, but there is a subtle difference between the two. Thermal imaging specifically detects the heat emitted by an object or surface, while infrared imaging refers to the use of infrared technology to capture images beyond the visible spectrum, which can include both thermal and non-thermal information.


What is the difference between infrared heat and infrared light?

Infrared heat and infrared light are both forms of electromagnetic radiation, but they serve different purposes. Infrared heat is a type of energy that produces heat when absorbed by an object, while infrared light is a type of light that is not visible to the human eye but can be detected by certain devices.


Is ther a difference between imaging and infrared imaging?

Not much. Some put the span of the IR spectra at a lightly different place than the thermal span, but the difference is marginal.
