Answer to Question 1

d,
The de Broglie wavelength of matter is proportional to Planck's constant and inversely proportional to the momentum of the particle. If all the objects had the same velocity, this one would have the smallest wavelength because its momentum would be smallest

Answer to Question 2

b.
X-ray scattering did not rule out the corpuscle model of light, but merely showed another use of light in investigating the structure of matter.
