Infrared telescopes, which use special infrared detectors, are able to peer farther into star-forming regions of the galaxy because infrared light is not scattered as strongly as is visible light by the tenuous clouds of hydrogen gas from which new stars are created.
For what wavelength of light is the scattering only 2.00% that of light with a visible wavelength of 490nm ?
The Attempt at a Solution
the formula is I(490)/IR=(lamda/490nm)^4.
I'm really not sure what I am doing wrong here
