Webb3 okt. 2024 · What are the properties of ultraviolet rays? Following are the properties of ultraviolet waves: The wavelength of ultraviolet waves is -1 x 10-8 to -4 x 10-7 metres. The frequency of ultraviolet waves is -7.5 x 1014 to -3 x 1016 Hz. The wavelengths of ultraviolet are shorter than the visible light. Thick clouds can block UV rays. WebbLight waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.
