Why don't we see the constellation Orion at night throughout
the year? - ANSWER-As the earth orbits the sun, its nighttime
side points to different constellations at different points along
its orbit
when is the best time for you to be able to see the constellation
that is your sign
of the zodiac - ANSWER-at middnight sex months after
your birthday
Constellations close to the north pole of earth___ - ANSWER-
Move in a circle
around the North star, Polaris, over the course of a
single night.
There are a total of 88 constellations. Roughly how many of
these can be seen
at any given time from a single location on a clear night? -
ANSWER-44
,A photon's___can be measured to determine its energy
- ANSWER-
wavelengths or
frequency
Which one requires more energy? Long or short waves? -
ANSWER-short
waves require more energy to
generate
A star(sun) has a surface area temperature of 50,000 kelvin, in
which region of
electromagnetic spectrum does its peak brightness
occur? - ANSWER-
Ultraviolet
Suppose I detect a star giving off more ultraviolet light than
infrared light. What property of the star can I estimate with this
infor? - ANSWER-its temperature
What is the relationship between wavelength and frequency? -
ANSWER-if the
frequency increases the wavelength
decreases
Compare frequency of x-ray versus regular light - ANSWER-
The X-ray has a
,larger frequency than
visible light.
Compare the frequency and wavelength of a gamma ray with
visible light: -
ANSWER-gamma ray frequency is higher and its
wavelength is lower
If the frequency of radiation is twice as large then its wavelength
is - ANSWER-
half as
large
Compared to blue light, red light has - ANSWER-longer
wavelength, smaller
frequency, smaller
energy
Which types of radiation have the lowest energy? - ANSWER-
infrared radiation
and
radio
Where rainbows come from? - ANSWER-a rainbow is a result
of white light
being split into its component parts of visible light
spectrum through mist
droplets
, in what region of the electromagnetic spectrum would an
object near Absolute
Zero radiate the most? -
ANSWER-radio
What would you expect an object at 600 kelvin to radiate the
most energy. -
ANSWER-Visible light b/c humans are about
310 kelvin
Electromagnetic Radiation / Light - ANSWER-Light has some
properties of a
wave and other properties of a
particle.
- A "particle of light" is called a
photon.
Forms of light, from high-energy to low-energy:
- gamma ray > X-ray > ultraviolet (UV) > visible > infrared (IR)
> microwave >
radio(DO
ACRONYM)
high-energy light =high frequency =low / short wavelength = a
bluer color
