What types of waves are electromagnetic waves?
Transverse.
What do electromagnetic waves transfer?
Energy
(not
matter
).
What type of spectrum do electromagnetic waves form?
A
continuous
spectrum.
List the order of the electromagnetic spectrum in order of increasing wavelength.
Gamma
, X-ray,
UV
,
Visible
, Infrared,
Microwaves
and
Radio.
What is the highest frequency electromagnetic wave?
Gamma
waves.
What is the highest energy electromagnetic wave?
Gamma
waves.
What properties are shared by all electromagnetic waves?
They are all
transverse
waves. They all travel at the same speed (
3x10
^
8
m/s). They can travel through a
vacuum.
What range of frequencies of electromagnetic waves can be detected by the human eye?
400-700
nanometres.
How do the speeds of EM radiation differ in a vacuum and in air?
Electromagnetic waves all
travel
at the
same
speed in a
vacuum
and in
air.
What can happen when radiation strikes an object?
It can be...
Transmitted
,
Reflected
and
Absorbed.
