Answers

1
What was the solution that Einstein offered to the photoelectric problem?
light is a wave, not a particle
electrons and light are equivalent via E=MC2
light is a particle, not a wave
light is structured into wave packets
2
Which of these did Einstein NOT substantially contribute to?
brownian motion
wave-particle duality
quantum entanglement
mass-energy equivalence
3
Which of these would you NOT observe as a train passed you at a velocity close to the speed of light?
Events on the train would be happening very slowly
light emitted by the train would be traveling at its usual speed
The train would be narrower in width and height than when it wasn't moving
The train would be shorter in length than when it wasn't moving
4
E=mc2 relates
the amount of energy in mass to the speed of light
none of these
energy of motion to momentum
the maximum speed of light to the energy of the vacuum
5
What was the odd phenomenon of the 'photoelectric effect'?
Light below a threshold frequency ejected no electrons
theory could not explain why light ejected electrons
light below a threshold intensity ejected no electrons
Higher energy light ejected fewer electrons
6
Which of these is NOT a principle of special relativity?
a gravitational field distorts spacetime
gravity and space are equivalent
The laws of physics are the same regardless of inertial motion
The speed of light is constant for every observer
