Re: HELP IN A HURRY!



Hot air does bend a beam away from the normal, BUT n for air does not
equal 1.
n air at 273 K is 1.0002926
n air at 298 K is 1.0002758 at 650 nm

At these precisions you have to account for the effects of wavelength
and pressure. (pressure is 1 atm in the above.)

Thus light does not go faster than c but still bends away from the normal.
