questions and Answers
What kind of photon is produced in annihilation? - Answer>>
gamma
State what roles exchange particles can play in an interaction -
Answer>> -Transfers energy
-transfers momentum
-Transfers force
What is pair production? - Answer>> Pair production is when
one high energy photon spontaneously turns into a particle-
antiparticle pair
Give one difference and one similarity between a negative muon
and an electron - Answer>> Difference: The muon decays but
the electron does not
Similarity: Both are negatively charged
What is the equation for the threshold frequency in terms of the
work function? - Answer>> f=work function/h
Explain why the strong nuclear force must be repulsive at very
short distances - Answer>> Because it would crash the nucleus
to a point
Describe the changes that happen in the nucleus during alpha
and beta-minus decay - Answer>> -alpha decay: proton number
decreases by two and the nucleon number decreases by four
, -beta decay: proton number increases by one and the nucleon
number stays the same.
Is the strong interaction attractive or repulsive at a nucleon
separation of 2fm? - Answer>> attractive
State what is meant by an isotope - Answer>> atoms with the
same number of protons but different number of neutrons
Describe the nuclear model of the atom? - Answer>> Inside
every atom there is a nucleus which contains protons and
neutrons. orbiting this are the electrons
How could you calculate the specific charge of a particle? -
Answer>> specific charge=charge/mass
Define the proton number and the nucleon number - Answer>>
proton number=how many protons there are in the nucleus
nucleon number=mass number. Tells you how many protons and
neutrons there are in the nucleus
What are the two types of hadrons? - Answer>> -Baryons
-mesons
Who proposed the photon theory of light? - Answer>> Albert
Einstein
What is the quark composition of a proton? - Answer>> uud
According to the wave theory of light, what should the maximum
kinetic energy of emitted electrons be proportional to? -
Answer>> Intensity
