Observation : Bright blue light liberates electrons 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 CORRECTLY EXPLAIN THE OBSERVATION?

• YES

• NO

NGSS.HS-PS4-3

Observation : Bright blue light liberates electrons 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 electrons

DOES THE EXPLANATION EXPLAIN THE OBSERVATION?

• YES

• NO
