It is both
Is electromagnetic radiation a
wave or a particle?
$600
Visible and radio
Two forms of
electromagnetic radiation that
penetrate the atmosphere best
are:
$800
Gamma rays
The part of the electromagnetic
spectrum with the shortest
wavelength is
$1000
White light is all the colors blended
together uniformly
What is white light?
$200
Rainbow
What is an example of a
classic continuous spectrum
$400
violet
The visible light with the
shortest wavelength is
$600
visible
What type of radiation can be
observed well from Earth’s
surface?
$800
red
Which color of electromagnetic
radiation has the longest
wavelength?
$1000
We don’t for sure. Since lightmust travelo
millions of light years, the light we see is
millions of years old.
How do we know that a star
in a distant galaxy is still
there?
$200
red
Objects we are moving away
from appear
$400
Doppler effect
When you hear a siren change
pitch as it approaches you
this is an example of
$600
No shift at all (not blue or red) so it will
appear yellow
The light from an object
moving from right to left will
exhibit
$800
blue
An object moving towards us
would appear
$1000
You can give its radial velocity, either towards
or away from us.
What information can be
inferred about a star from its
Doppler shift?
$200
radio
What type of wave has the
lowest energy
$400
halved
If a waves frequency doubles
it wavelength is
$600
They both transfer energy.
Sound needs a medium, light travels in space
How are sound waves and
electromagnetic radiation
similar? How are they
different?
$800
Frequency times the wavelength
A wave’s velocity is the product of the
$1000
Sound travels through a material medium,
and can not travel through a vacuum
Why can you hear a tree fall
in the forest but you can’t
hear me slam the space
capsule door in space?
$200
Photon
Individual packet of
electromagnetic radiation

Spectroscopy
An analysis of the way atoms
absorb and emit light is
$600
Kelvin
Temperature scale that places
zero at the point where all
atomic motion ceases.
