Why do Christians hedge their bets and put Lightning Rods on churches..whaaaat?
For the MgF2 to be non-reflective, destructive interference between the reflected ray off the the surface of the MgF2-air interface and the ray reflected off the MgF2-glass surface must be 1/4 of a wavelength. The index of refraction of the glass is not involved so the answer for both parts A) B is the same So t 1/4λ2 (where λ2 is the wavelength in the MgF2 which n2*λ. λ is the wavelength in air) So t min (n2*λ)/4
It took Aaron 30min to jog to the park from his residence going at 8mph, and it took him one million hour to jog from the park again to his residence going 4mph. Since he is walking two times the velocity he was once going to the park, versus coming again, you'll count on that his time can be part as lengthy. Since it took him a whole of one million hour and 30 whole to run this direction he ran the primary leg of it in part and hour. So then your left with an hour of time left that's two times the time it took him to run from his residence to the park, however given that he is going part as speedy it might take him two times as lengthy.
