a. 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.
