Waves with a frequency higher than visible light are classified as ultraviolet (UV) waves, which fall just beyond the violet end of the visible spectrum. UV waves are characterized by their higher energy levels and shorter wavelengths, ranging from about 10 nm to 400 nm. They are significant in various fields, including medical applications and sterilization processes, due to their ability to kill or inactivate microorganisms. Exposure to UV radiation can have both beneficial and harmful effects, such as stimulating vitamin D production in the skin while potentially causing skin damage.
