PLEASE HELP
medical xrays, with a wavelength of about 10^10m, can penetrate completely through your skin.
Ultra violet rays, which cause sunburns by penetrating only the top level of skin, have a wavelength about 1000 times the wavelength of an xray. find the wavelength of ultraviolet rays. show your work.
Hint: scientific notation.

Best ResponseYou've already chosen the best response.0so it would be (1 x 10^10)(1 x 10^3) ? which simplifies to 1 x 10^7?
