Ultraviolet rays, which cause sub 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 the ultraviolet rays.

X-ray wavelength = 10^-10

please show me how to find the wavelength of the ulraviolet ray

Question

Ultraviolet rays, which cause sub 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 the ultraviolet rays.

X-ray wavelength = 10^-10

please show me how to find the wavelength of the ulraviolet ray

anonymous · Answer

also this too! 
The wavelength of visible lights are between 3.8 X 10^-7 m and 7.6 x 10^-7 are these wavelengths longer or shorter than those of vltraviolet rays?

anonymous · Answer

UV wavelength=1000* X-ray wavelength
X-ray wavelength=10^-10
so, UV wavelength= 1000*10^-10
                          =(10^3)*(10^-10)=10^-7

anonymous · Answer

visible light wavelength longer than UV

anonymous · Answer

why is it longer? explain

anonymous · Answer

wave length $$\lambda$$ has inverse relation to the frequency f, you can check the attached file have a better sight
