Web7 de abr. de 2024 · It has a frequency ranging between 800 THz to 30 PHz. According to physics, UV radiation is divided into four regions - Near (400 – 300 nm) Middle (300 – 200 nm) Far (200 – 100 nm) Extreme (below 100 nm) On the interaction of ultraviolet radiation wavelength with biological materials, it is divided into three divisions - UVA (400nm – 315 … WebLight waves also come in many frequencies. The frequency is the number of waves that pass a point in space during any time interval, usually one second. We measure it in units of cycles (waves) per second, or hertz. The frequency of visible light is referred to as color, and ranges from 430 trillion hertz, seen as red, to 750 trillion hertz ...
