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?
Is light composed of particles or waves?
Atomic electrons have specific allowed energy
If atoms occupy only certain allowed levels, how
do they get from one allowed level to another?
Why do atoms emit or absorb only certain specific
colors of light?
How can you tell that there is calcium in the atmosphere
of the star Betelgeuse, which is about 310 light years
away from the earth?
Why is it that you are transparent to radio waves,
more and more opaque as the frequency increases
to the visible and ultraviolet part of the spectrum,
and then suddenly transparent again when you get
to the xray part of the electromagnetic spectrum?
Why do you say that ultraviolet exposure might involve
some risk of skin cancer, whereas exposure from your
microwave oven carries no such risk?
What types of radiation make up the ionizing radiation
which we might be exposed to?
What is a laser?
What are the characteristic properties which make
the light from a laser unique?
What is a hologram? What properties distinguish a
hologram from an ordinary photograph?
