## newbold_galen one year ago medical x-rays, with a wavelength of about 10^-10m, can penetrate completely through your skin. -ultraviolet rays, which cause sun burn by penetrating only the top level of skin, have a wave length about 1000 times the wavelength of an x-ray. find the wavelength of ultraviolet rays. (need to show work)

1. ash2326

X rays wavelength= $$10^{-10} m$$ UV rays have a wavelength 1000 times that of X-ray so UV rays wavelength=$$1000\times 10^{-10} meters$$ Can you simplify this?

2. newbold_galen

$1\times10^{-3}\times10^{-10}$

3. newbold_galen

$so 1\times10^{-13^{?}}$ ?

4. ash2326

$10^3\times 10^{-10}=10^{-7}$

ok i get it! thank you
