Is light composed of particles or waves?

Describe the photoelectric effect. How does it indicate that light is composed of particles?

What aspects of the photoelectric effect experiment were surprising to the classical physicists of the day?

What is "blackbody radiation"? How does the "particle" view of light help explain it?

The failure of classical physics to explain blackbody radiation is called the "ultraviolet catastrophe". Explain the implications of this phrase.

What is a quantum of light called and what is the relationship which characterizes it?

How do you determine the temperature of a hot object using the blackbody radiation curve?

If light exhibits both particle and wave behavior, what about electrons - do they show a dual nature as well?

If an electron acts like a wave, what is the wave, i.e., what is waving?

What is meant by the "wavefunction" for a particle?

What can be learned from the wavefunction?

What is the significance of the wavelength of the wave associated with an electron?

What are the implications of the uncertainty principle for the observation of electron position and momentum?

Can an electron exist inside a nucleus? The Schrodinger equation for a particle in a box gives some insight.
