Conta
+ directed normally at a diffraction grating
tains wavelengths of 580 and 586 nm only. The
grating has 600 lines per mm.
How many diffracted orders are observed in the
transmitted light?
For the highest order, calculate the angle between
the two diffracted beams.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
