I. Electromagnetic Waves (EM)
(including light waves)
a.The EM spectrum is a
continuous range of waves
extending from radio waves
(low frequency/high
wavelength) to gamma rays
(high frequency/low
wavelength).
b. All EM waves move with
the same speed, c= 3x108
m/s, through a vacuum.
c. The energy of each EM
wave is proportional to the
frequency and give by, E=hf
where h=Planck’s constant.

with small amplitudes they
can be modeled as
transverse waves.
d. Wave quantities of
speed, wavelength,
frequency, and amplitude
can be defined by
examining wave diagrams.
The speed, wavelength and
frequency are related by
the equation, v=f.
e.Frequency can be observed
as the pitch of a sound
wave or the color of a light
wave.
f. Amplitude can be observed
by the loudness of a sound
wave or the intensity of a
light wave.

culmination of many scientific
investigations drawing together
all the current evidence
concerning a substantial range of
phenomena; thus, a scientific
theory represents the most
powerful explanation scientists

to constructive interference
(two crests make a larger
crest or two troughs make a
larger trough) or destructive
interference (a crest and a
trough partially or fully
cancel each other).
e.Doppler Effect – The
APPARENT change in the
frequency of a wave due to
motion of the source and/or
observer. Examples include
the change in pitch of a race
car engine as it
approaches/recedes from a
microphone and the red
shift/blue shift of stars and
distant galaxies as they
move relative to us.
f. The red shift of every
distant galaxy was part of
the evidence used to
theorize that the universe is
constantly expanding and
thus must have originated
as a singularity that
exploded in a big bang.
