UV Full Form - Ultraviolet

 Ultraviolet

Ultraviolet

  • The full form of UV is Ultraviolet. UV light features a wavelength of 10 to 400 nm, which is shorter than the light but longer than the X-rays and may be a form of electromagnetic wave.
  • They're found in sunlight and produce 10% of the light from the entire sunlight.

Ultraviolet Waves Properties

  • Ultraviolet is one among the electromagnetic wave produced by the Sun and distributed either as waves or as particles of specific frequency and wavelength. The UV wave characteristics are as follows.
    • UV light wave ranges are -1 x 10-8m to -4 x 10-7m.
    • UV light wave frequency is from -7.5 x 1014 Hz to -3 x 1016 Hz.
    • UV light wavelengths are narrower than visible light.
    • Thick clouds can block ultraviolet radiation.
    • In clinics and laboratories, a UV light is used as a disinfectant.
    • Nearest to the light is that the near-ultraviolet.
    • The Far-ultraviolet exists between UV near and extreme areas.

Ultraviolet Discovery

  • One very fascinating story is that the detection of UV radiation. A gentleman named Johann Ritter had tried to verify the presence of waves beyond the visible spectrum in the 1800s.
  • It had been known and understood that film changed to black in blue light more easily than red.
  • Ritter exposed that film to beyond violet, and therefore the film changed color needless to say. This confirmed UV rays exist.

Use of UV rays

  • UV lamps emit light which is sufficient to destroy the germs.
  • UV lights are used for sterilizing surgical equipment in hospitals.
  • Ultraviolet light is additionally used for water treatment and therefore the pharmaceutical sector.

Advantages of UV

  • The human body requires UV from the Sun to produce vitamin D. Vitamin D aids make stronger bones, muscles and system of the body.
  • The cure for skin conditions is completed by using UV like psoriasis. The shedding of cells too rapidly and therefore the development of itchy and scaly patches by the skin occur in this condition. The expansion of the skin cells slows down and relieves the symptoms due to revelation to UV.
  • To produce certain chemicals called 'tryptamines', the daylight stimulates the pineal body within the brain suggested by the research. Enhancement of an individual's mood is happened by these chemicals.
  • To trace many ripe fruits, flowers, and seeds that emerge out more strongly from the background, few animals comprising birds, bees and reptiles are capable of to watch into the near UV light.
  • As a reference for navigation on the wing, many insects use UV emissions from celestial objects. This is often the reason; a light-weight sometimes attracts flying insects by making troublesome in their navigation process.

Disadvantages of UV

  • UV is an ecological human carcinogen. It is the most significant and widespread cancer-causing agent in our surroundings.
  • When skin cells are damaged then there's a burn occurs which is named Sunburn. The absorption of energy from UV rays is caused by damage to the skin.
  • On the system, over-exposure to UV radiation features a detrimental suppressing outcome.
  • Damaging of the tissues of eyes occurs due to extended revelation to UV or high intensities of UV and may become a reason for a 'burning' of the attention surface, which is named as 'snow blindness' or photokeratitis.
  • UV destroys the collagen and connective tissue under the highest layer of the skin which accelerates the aging of the skin.
  • Lots of polymers used in consumer items comprising plastics, nylon, and polystyrene are wrecked down or be unable to find strength due to revelation to UV light.
