Question

Write properties of ultraviolet waves.

Answer 1

Hint:To answer this question, we first need to understand what are waves.A wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities in physics, mathematics, and related subjects, commonly described by a wave equation. At least two field quantities in the wave medium are involved in physical waves. Periodic waves occur when variables oscillate periodically around an equilibrium (resting) value at a specific frequency.

Complete answer:
Ultraviolet waves - UV is a type of electromagnetic radiation with a wavelength ranging from 10 nm to 400 nm, which is shorter than visible light but longer than X-rays. UV radiation is found in sunshine and accounts for around 10% of the Sun's total electromagnetic radiation output.

Electric arcs and specialty lights, such as mercury-vapor lamps, tanning lamps, and black lights, can also produce it. Although long-wavelength ultraviolet light cannot ionize atoms because its photons lack the energy to do so, it can initiate chemical processes and make many things light or fluoresce. As a result, UV has more chemical and biological impacts than simple heating.

Properties of ultraviolet waves:
-Ultraviolet waves have a wavelength of 10-nm to 400-nm.
-Ultraviolet light has shorter wavelengths than visible light.
-UV rays can be blocked by thick clouds.
-In hospitals and laboratories, UV light is utilized to sterilize surfaces.
-The near-ultraviolet spectrum is the most similar to visible light.
-Between the near and extreme ultraviolet zones is the far ultraviolet.

So, we conclude that the wavelengths of ultraviolet (UV) light are shorter than those of visible light. Although UV wavelengths are undetectable to the naked eye, they are visible to some insects, such as bumblebees.

Note: UV radiation can cause a variety of health concerns in addition to skin cancer: Premature ageing of the skin and symptoms of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis can all be caused by UV exposure. UV rays can also harm your eyes.
