Here is the question.
Medical X-rays, with a wavelength of about 10^-10m, can penetrate completely through your skin.
a. Ultraviolet rays, which cause sun burn by penetrating only the top level of skin, have a wavelength about 1000 times the wavelength of an x-ray. Find the wavelength of visible rays. Show your work.
b. the wavelengths of visible light are between 3.8 x 10^-7m and 7.6 x 10^-7m. Are these wavelengths longer or shorter than those of ultraviolet rays? Explain.
If anyone can help I would be forever greatful. I have been trying to figure this out for 2 days and have not had any luck.
