These applications, while seem helpful, can be more dangerous than helpful if not used with extreme caution. Required fields are marked *. Most of us have heard of ultraviolet (UV) light. Generally, radiation with wavelengths much shorter than visible light have enough energy to strip electrons from atoms. Order is as follows (shortest to longest wavelength): Gamma, X-Rays, UV, Visible, Infrared, Microwaves, Radio Waves. While they are more likely to cause sunburn, they take a certain level of exposure before this occurs. Broad-spectrum sunscreen, clothing, and sunglasses can help prevent damage caused by UVA and UVB light. What are the different types of UV Light? Scientists call this ionizing radiation. UV light, however, falls just short of this. 10^(-34) Js^-1) f=frequency of the wave Hence we can see that the energy of a wave is proportional to its frequency, as the other term is a constant. But did you know there are different types of UV light? The detailed . DISCLAIMER: The Radio Prepper logo (depicting a microphone) is indeed inspired from a famous flag created in 1775. Question 6. Radio frequency (RF) energy at power density levels of 110mW/cm2 or higher can cause measurable heating of tissues. This means your windshield and windows provide little protection from exposure.
