Question 2

What was the conclusion of Feynman's first thought experiment regarding waves and particles, in which indestructible bullets are fired from a wobbly gun at a pair of slits?
a. When both slits are open, the total of bullets in this sand is the sum of bullets shot through one slit and the other.
b. A bullet through one slit affects the probability that the next bullet goes through the same slit.
c. Bullets rebounding from closed slits show refraction patterns.
d. When both slits are open, interference patterns keep the number of bullets from reaching the full number shot one slit and then the other.
e. Three times as many bullets go through two open slits as through one and then the other.
