Photoelectric Effect
Wavefunctions
Particle in a Box
100

The property of light that needs to be large enough for the photoelectric effect to occur.

What is frequency?

100

This person predicted that, if light can have particle-like properties, then matter can have wave-like properties.

Who is DeBroglie?

100

This is a coordinate for a wavefunction that leads to a zero-probability for that location.

What is a node?

200

The property of light that, surprisingly, does not determine whether or not the photoelectric effect occurs.

What is intensity?

200

Particles with this property in common will have measurable (but still small) wavelengths according to the DeBroglie equation.

What is small mass?

200

This is the average location of a particle in a box, regardless of the particle's particular energy state.

What is a/2?

300

This equation correctly predicts the photoelectric effect.

What is KE = h nu - phi

300

This property for a particle is proportional to the wavefunction "squared."

What is probability?

300

This is the average momentum of a particle in a box, regardless of the particle's particular energy state.

What is 0?

400

The photoelectric effect is an example of experimental evidence in support of this model of light.

What is the photon model?

400

This property of a system is determined from the second-order derivative of the wavefunction.

What is the energy?

400

These are the two ways that the (generally nonclassical) 1D PIB system can be made to behave more like a classical system.

What is increase the energy level or increase the size of the box?

500

This is what happens to the kinetic energy of electrons emitted when the intensity of light is increased.

What is nothing?

500

These are the four requirements for a wavefunction to be acceptable.

What are single-valued, continuous, finite, and normalizable?

500

This property of a 1D PIB system should be maximized when we wish to minimize momentum uncertainty, but this will have the unavoidable effect of increasing positional uncertainty.

What is the box length?
