Ok so on this what do I do
(Please don't give me the answer I just want to know what I need to do on it)
Medical Xrays, 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 wavelength about 1000 times the wavelength of an Xray. find the wavelength of ultraviolet rays. Show your work.

Best ResponseYou've already chosen the best response.2It seems too simple, but, you just do what the problem says, and, it seems it *explicitly* says '1000 times the...' which would normally indicate that you multiply by a factor of 1000.

Best ResponseYou've already chosen the best response.0Well I asked if I multiply 10^10 * 1000 and you said you think so :P

Best ResponseYou've already chosen the best response.2Yes, that's true, but how exactly did you arrive at your answer? \[\Large \left.\begin{matrix}10^{10}\cdot 1000&=&100 \ 000 \ 000 \ 000 \ 000\\&\color{red}?&\end{matrix}\right. \]

Best ResponseYou've already chosen the best response.0First I multiplied out 10^10 and got 100,000,000,000 then I multiplied it by 1000 and got 100,000,000,000,000

Best ResponseYou've already chosen the best response.2Sorry... the problem here is that the exponent was negative... so it's not as straightforward as simply 'multiplying out'

Best ResponseYou've already chosen the best response.2That's right :) Now multiply THAT to 1000. And let me take the liberty of reminding you that \[\Large 1000 = 10^3\]

Best ResponseYou've already chosen the best response.2\[\Large 10^{10}\cdot 10^3\] First law of exponents... when you multiply, with same base, ADD the exponents.

Best ResponseYou've already chosen the best response.0Can you please help me on this one to? the wavelengths of visible light are between 3.8 * 10^7m and 7.6 * 10^7m. Are these wavelengths longer or shorter than those of ultraviolet rays? Explain On it do I need to simplify each scientific notation out and just put how I simplified them and put what one is bigger?
