Direction: Solve the problem given. Type in your final answer on the box and submit your solution in the folder.
Problem:
A sodium surface is illuminated with light of wavelength 0.300 mm. The work function for sodium is 2.46 ev. Calculate the maximum kinetic energy of the
ejected photoelectrons.
Answer: \blank nm.
Answer: 1.67
Direction: Solve the problem given. Type in your final answer on the box and submit your solution in the folder.
Problem:
X-rays of wavelength 0.200 000 nm are scattered from a block of material. The scattered x-rays are observed at an angle of 45.0° to the incident beam.
Compute the fractional change in the energy of a photon in the collision.
Answer: -3.54x10^-8
Direction: Solve the problem given. Type in your final answer on the box and submit your solution in the folder.
Problem:
Singly ionized helium,Het, a hydrogen-like system, has one electron in the orbit corresponding to n = 1 when the atom is in its ground state. Find the
energy of the system in the ground state in electron volts.
