What is ultraviolet ray?

Immediately after understanding the word science, we hear the word ultraviolet rays. As we know, even though there are many wavelengths of light, we only see light rays or a spectrum of wavelengths in the visible region. In which there are seven different letters. Where the shortest wavelength is violet light and the longest wavelength is the red light.

But this is a little less than violet light and light rays with wavelengths outside our visual range are – ultraviolet rays or Ultraviolet Radiation. Its wavelength ranges from about 100 nanometers to 400 nanometers. Light rays in the ultraviolet range, which have longer wavelengths, have the ability to penetrate the Earth’s atmosphere.
