What are UV rays? Harmful effects of ultraviolet rays and how to prevent them

UV (Ultraviolet) rays, also known as ultraviolet rays, UV rays are electromagnetic waves from the sun with wavelengths shorter than that of light. The spectrum of ultraviolet rays can be divided into two regions: the ultraviolet region and the near ultraviolet region. UV rays are also known as ultraviolet rays. We can use UV Meter to measure the intensity of ultraviolet rays.
