Describe Planck’s quantum concept by completing the following
statement.
The quantum concept concludes that matter can gain or lose
only in small, specific amounts called
.
A quantum is the minimum amount of energy that can be
or
by an atom.

Compare and contrast Einstein’s equation with Planck’s equation
by completing the following sentence.
, demonstrates mathematically
Planck’s equation,
that the energy of a quantum is related to the
of
the emitted radiation. Einstein went further by explaining that, in
addition to its wavelike characteristics, a beam of light can be
thought of as a stream of
called
.
Contrast the continuous electromagnetic spectra and the atomic
emission spectra.
