Observation : Bright blue light liberates photoelectrons from
the surface of lithium but red light from the
same intensity does not give off any electrons
at all.
Explanation : The intensity of red light is not sufficient to
liberate photoelectrons
DOES THE EXPLANATION EXPLAIN THE OBSERVATION?
YES
NO
Observation : Bright blue light liberates photoelectrons from
the surface of lithium but red light from the
same intensity does not give off any electrons
at all.
Explanation : Photons of blue light carry more energy than
photons of red light because the frequency of
blue light is higher than the frequency of red
light
DOES THE EXPLANATION EXPLAIN THE OBSERVATION?
YES
NO
