Please explain to me how to do B. I have done A. and got 10^-7 A. 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 wavelength about 1000 times the wavelength of an X-ray. find the wavelength of ultraviolet rays. Show your work. B. 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

ok ... i thought it because it includes X-rays

If you put the wavelengths in fractional form the answer should be obvious: \[uv\ wavelength=\frac{1}{10^{7}}\] \[visible\ light\ wavelength\ range=\frac{3.8}{10^{7}} \to\ \frac{7.6}{10^{7}}\]

Is 1/10^7 m longer or shorter than 3.8/10^7 m ?
anonymous
  • anonymous
Shorter
kropot72
  • kropot72
Correct! And is 1/10^7 m longer or shorter than 7.6/10^7 m ?
anonymous
  • anonymous
Shorter
kropot72
  • kropot72
Correct again. So you have found that the wavelength of ultra-violet rays is shorter than the wavelength of all colors in the spectrum of visible light.

Ok so what would I put for B
kropot72
  • kropot72
The wavelengths of visible light are longer than the wavelength of ultra-violet light.
