Medical xrays, with a wavelength of about 10-10m (Negative 10 is a exponent), can penetrate through your skin. ultraviolet rays, which cause cause sun burn by pentrating through the top layer of skin, have a wavelength of about 1000 times the wavelenth of of an xray. find the wavelength of ultraviolet rays. Show your work. the wavelengths of visible light are are between 3.8 x 10-7 (negative 7 is the expotent) and 7.6 x 10-7 (Negative 10 is the expotent) are these wavelengths shorter or longer then the ultraviolerays? Show your work. How can you write 1000 using an exponent? What property can you use to multiply the expressions with exponents? How can you compare numbers written in scientific notation? Solution it ranges from 10nm to 400nm.... .
