Ultraviolet rays, which cause sun burn by penetrating only the top level of skin, have a wavelength about 100 times the wavelength of an X-ray. Find the wavelength of ultraviolet rays. Show your work. The wavelengths of visible light are between 3.8 × 10-7m and 7.6 × 10-7 m. Are these wavelengths longer or shorter than those of ultraviolet rays? Explain.

    You got the wavelength of the ultraviolet rays? Are the wavelength bigger than 7.6 * 10^-7 or smaller than 3.8*10^-7 or maybe just between?

    The wavelength is \[10^{-7}\]

    Well 10^-7 = 1 * 10^-7 which is less than 3.8 * 10^-7 This means that ultraviolet is shorter than the visible light.
