Astronomy Packet Light
1) Light is properly called the
________________________________________________________. Light itself travels
through space as______________. One of the measurable qualities is _______________ which
tells you the length of the ________. While _______________ tells you how many cycles are
produced per second. These two qualities are _____________ related and can be used to
calculate the__________________ of the ______________________. I
The type of radiation with the longest _________________ are ____________________.This
type of radiation is used by cellphones _____________ and _________ stations. The telescopes
used to observe this form of radiation look like large _____________________________. The
largest of this type of “telescopes” is located in _____________________________________.
Using this type of radiation astronomer have discovered ___________________ which are the
remenants of ___________________ which omit___________ of this form
radiation__________. A second major discovery made through form of radiation are
____________________________.
The second form of radiation discussed was _____________________ which was discovered
by____________________________________________________________________________
__ ___________________________________________________________________________.
Commercially this form is used to ______ food by________ the molecules of____________
until the change ________. Astronomically it has been used to see the ____________ of the
Big Bang, which shows the ________________________________ which gives empty space a
temperature of _______ K
The next major form of radiation we discussed was _____________________ which is
basically ______________________________and is produced by almost all objects. This form
of radiation is used by the military for___________________ as well commericially as
________ vision. The main telescope used to observe this form of radiation is
_____________________. This has allowed us to view the center of our
_____________________ as visible light is blocked by the large amounts of. _________
and__________ located between us and it.
Most of the astronomical data we collected during our history has been made in the
___________ part of the ________________________. This part of the spectrum is broken in to
the familiar __________ which are ( from longest wavelength to shortest______ _______
_______ ________ _________ _______ ______or __________ for short. Two of the largest
telescopes which use this form are ____________________ and the twin___________ in
Hawaii
2) The next form of radiation discussed was ________________ or ____ for short. There are
___ types of this radiation but only____ penetrate our atmosphere. The main telescope used to
observe this type of radiation is _________________. Using this type of radiation we have
been able to discover _____________and _________.Human use this type of radiation
for_______________ and______________ Unfortunately exposure to large amounts of this
form of radiation has been linked to ____________________ as this radiation causes
_____________________in __________. But small doses of this radiation are beneficial in the
synthesis of Vitamin __ which is used by the body for____________________________.
The next form of radiation we discussed was _________________ which was discovered
by__________________________ and used to take an image of his
__________________________________ now known as the 1st ______. This type of radiation is
used today to take images of ____________________ in the medical field. In terms of
astronomy the main “telescope” used to observe this form of radiation is _______________.
Using this type of radiation astronomer have studied__________________
and_______________ as well providing evidence for____________________ and more image
about the __________of our galaxy. The final form of Radiation we discussed was__________
which was originally though to only occur during __________decay or explosions. It was
discovered in space by the _______ during the ________________ while we were looking
for___________________. We found them but deep in ________ , thes_____ wer incredibly
powerful and are now attributed to ____________ and ______________and
_______________________ The 2 main satellites used to study this form of radiation are
_________ and ___________ .
3) Astronomers use_____________________ to calculate the Surface temperature of celestial
objects. Other tools used astronomers to study distance objects makeup are ___________
and________ spectral analysis. This tool allows scientists to understand what the
_____________ makeup of a star or the composition of the_____________ of a planet.
