Answer 2

Properties:-

1. Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.

2. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact.

Uses:-

1. UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.

2. Different UV wavelengths and intensities are used for different purposes.
