What is meant Minimum energy required by an
by work electron to escape from (1) a
function (2) metal surface (1)
What is meant Minimum energy required to
by ionisation remove an electron from an atom
energy? (2) (1) from the ground state (1)
, Energy of a photon is
fixed/constant (1)
Why do
Energy is required for electrons
emitted
to overcome work function ø (1)
electrons have
Electrons deeper into/below the
a kinetic
surface of the metal require more
energy that
energy to overcome work
varies up to a
function and therefore have less
maximum
KE(1)
value? (4)
Maximum KE = Energy of photon
- work function ø (1)
Explain how Diffraction pattern
(bright ring) maxima/minima (bright and dark
diagram is areas) (1)
evidence of Diffraction is a property of
the wave- waves- proves wave-behaviour of
particle duality electrons (1)
of electrons?
What is meant The lowest energy state of an
by the ground atom
state?
