In the double-slit experiment with light, suppose that the light source is turned on so briefly that only a single quantum of energy passes through the double slits. When it arrives at the screen, this energy is deposited
A) all over the white interference bands that normally appear in the double-slit experiment.
B) at one small point, which could be anywhere on the screen.
C) at one small point within the white interference bands.
D) all over one of the white interference bands.
E) at one small point, lying directly behind the slit through which the energy came.
Question 2
At what temperature would the root-mean-square speed of hydrogen, H2, molecules equal 11.2 km/s (the earth's escape speed)? The mass of a hydrogen atom is 1.67 10-27 kg, and the Boltzmann constant is 1.38 10-23 J/K.
A) 1.01 102 K
B) 1.01 104 K
C) 1.01 106 K
D) 1.01 108 K
