Please explain this simply for me!
Medical xrays, with a wavelength of about 10^(10) m, 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 1,000 times the wavelength of an xray. Find the wavelength of ultraviolet rays. Show your work.

10^10 x 1000 100 = 10^3 so 10^10 x 10^3 add exponents... 10^7 m am i right?

Thanks! There's a second part  b. The wavelengths of visible light are between 3.8 x 10^(7) m and 7.6 x 10^(7) m. Are these wavelengths longer or shorter than the ultraviolet rays? Explain.

ultraviolet rays is 0.000010 m 0.00000038<visible light<0.00000076 which do you think is longer/shorter?

I know, I know. and I hate Algebra on top of this all, it's confusing. The next question confuses me even more! DX

Wait a second. You just calculated that UV light has wavelengths of \( 10^{7} \) meters. That is: \[ 1 \times 10^{7} \ m \] Then you're told that visible light has wavelengths such as \[ 3.8 \times 10^{7} m \] and \[ 7.6 \times 10^{7} \ m \] Clearly therefore, because 3.8 > 1 and 7.6 > 1, visible light has a longer wavelength.

But the lengths that are being compared are ultraviolet and medical xray.

Yes. I just showed you why visible light has a longer wave length. Do you agree with that? Then because \[ 10^{10} < 10^{7} \] it must be that xrays also have a shorter wave length than visible light.
