they words, a medium to transport the energy of
the wave.
(ocean & sound waves,
vibration)
Electromagnetic wave ( Correct answers ) do not require a medium to
transport
energy of the
the wave. They can travel both through matter and through a
vacuum (in
absence the
of matter.) An electromagnetic wave is a combination of an
oscillating
field and an electric
oscillating magnetic

photons)
Radio wave ( Correct answers ) have the longest wavelengths of all
EM radiation,
lowest frequency, lowest energy of
all EMs
Microwave ( Correct answers ) have wavelengths that are shorter than
those of radio

than those of
infrared
radiation.
Infrared wave ( Correct answers ) (IR) has wavelengths that are longer
than those

microwaves.
visible light.
-Although we cannot see this radiation, we can feel it through our
skin as heat.
Visible light ( Correct answers ) is a very small portion of the EM spectrum.
It includes
all of the wavelengths of light that the average unaided human eye
can detect.
Ultraviolet wave ( Correct answers ) (UV) has wavelengths that are just
shorterofthan
those visible violet light, but longer than those
of X-rays.
-The greatest source of UV radiation on the earth is
the sun.
