Describe the Uses of Infrared Visible Spectrum and Ultraviolet Rays

Ultraviolet waves are short and are used for purification forensic. With h the Plancks constant and f the frequency of the electromagnetic wave.

On the other hand while UV does not warm the body it does cause sunburn.

. Our eyes detect visible light. Restaurants use infrared lamps to keep buffet-style foods at a safe temperature for consumption. Visible light VL range Visible light wavelengths can be perceived by the average human eye.

Light also referred to in professional literature as radiation is best thought of as a spectrum consisting of ultraviolet light UV at the short end visible light in the center and infrared IR wavelengths at the long end. IR and UV radiation are a small part of the electromagnetic spectrum. Infrared IR light is used by electrical heaters cookers for cooking food short-range communications like remote controls optical fibres security systems and thermal imaging cameras which detect people in the dark.

Infrared rays are used for warming the skin and for relaxing the muscles. Aside from sight there are other important uses for visible light. ULTRAVIOLET LIGHT FROM OUR SUN.

The area next to the visible light with a shorter wavelength is the UV spectrum. UV light is measured in microwatts of ultraviolet radiation per lumen of visible light µWl. The energy of these spectral bands are related through the Einstein-Planck formula.

The majority of the IR radiation on earth comes from the sun. Hot objects in space. Infrared rays are used as a source of heat and to discover areas of heat differences.

It has frequencies of about 4 1014 to 8 1014 hertz Hz and a wavelength of about 740 nanometers 29 105 inches to 380 nanometer 15 105 inches. The visible spectrum is the portion of the. The key difference between infrared and ultraviolet radiation is that the wavelength of infrared radiation is longer than that of visible light whereas the wavelength of ultraviolet radiation is shorter than the wavelength of visible light.

In space infrared light helps us map the dust between stars. We concentrate visible light to make lasers to use in everything from. Reptile habitats at zoos are often kept warm with infrared lamps.

The visible light has a wavelength of 380 nm to 760 nm. Describe the uses of infrared visible spectrum and ultraviolet rays. A mug of tea is heated in a microwave oven.

Neither UV or infrared can be detected by the human eye but both have an effect on the body but in very different ways. Night vision goggles pick up the infrared light emitted by our skin and objects with heat. It is therefore generally invisible to the human eye although IR at wavelengths up to 1050 nanometers nms from specially pulsed lasers can be seen by humans under certain conditions.

The Sun is a source of the full spectrum of ultraviolet radiation which is commonly subdivided into UV-A UV-B and UV-C. Ultraviolet radiation UVR is characterized bywavelengths between 10 and 400 nm-bordered on the one side by x rays and on the other by visible light Fig. Explain why the tea gets hotter than the mug.

The fact that water vapor and other greenhouses gases absorb infrared is part of why the greenhouse effect happens. The optical radiation range is located between microwave radiation and X-rays. Visible light falls in the range of the electromagnetic spectrum between infrared rays and ultraviolet rays.

11 Optical radiation Optical radiation is radiant energy within a broad region of the electromagnetic spectrum that includes ultraviolet UV visible light and infrared radiation. UV-C rays are the most harmful and are almost completely absorbed by our atmosphere. Infrared IR sometimes called infrared light is electromagnetic radiation EMR with wavelengths longer than those of visible light.

Difference between radiotherapy and chemotherapy. Describe the uses of infrared visible spectrum and ultraviolet rays. Infrared radiation is used in applications such as lasers medical imaging computer accessories eg.

While Infrared warms the body it does not burn the skin or damage the cornea. Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. The area alongside with a longer wavelength is the IR spectrum.

All are electromagnetic waves. Infrared waves are long and are used for thermal imaging. Its all down to the frequency and energy in the waves.

Since the frequency of infrared is frequency of visible frequency of ultraviolet from the Einstein-Planck relationship it follows that the energy of infrared. E h f. Infrared rays are preferred because of their penetration quality through the skin.

The optical radiation range is composed in order of increasing energy of infrared visible and ultraviolet radiation. This imaging is done for objects that are placed in the near-infrared spectrum. Radio waves are very long.

Infrared filters are used for capturing pictures in infrared photography. Hope it is helpful. How can infrared radiation be detected if cannot be seen.

You cannot see infrared radiation but your skin senses it as warmth. Describe the uses of infrared visible spectrum and ultraviolet rays - 23227225 Aech8009 Aech8009 1 week ago Science Senior High School answered Describe the uses of infrared visible spectrum and ultraviolet rays 1 See answer Advertisement. What is meant by visible spectrum.

The electromagnetic spectrum spans many orders of magnitude in energy and correspondingly in frequency and wavelength. Fireflies light bulbs and stars all emit visible light. Infrared and ultraviolet radiation are two types of electromagnetic radiationThis means these radiation waves have.

These are the classifications most often used in Earth sciences. We use infrared radiation in many ways including thermal imaging cameras remote controls fiber optic cables infrared astronomy and meteorology.
