WebUV-light can be further divided into three categories based on their wavelengths: UVA, UVB, and UVC. UVA, known as long-wave UV radiation, is responsible for tanning and premature aging of the skin. UVA radiation has a wavelength range of 320-400 nm and accounts for 95% of the UV radiation that reaches the Earth's surface. WebThe Electromagnetic Spectrum - Ultraviolet Rays. UV rays lie in the wavelength range from around 10 nm to around 400 nm and have a frequency between the ranges 800 THz to 30 PHz. UV radiation is harmful as continuous exposure to these will result in skin and eye diseases. It also results in the aging of the skin.
