Conceptual Physics II, Day 6

LIGHT Is a wave ... Is a particle ... phenomenon?
Rayleigh criteria

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?

*Wave particle duality

*Rayleigh criterion

*Photoelectric effect

*Blackbody radiation

*Rayleigh-Jeans law
