Name this property of a light wave.
Wavelength
100
Define spectroscopy
The study of the properties of light that depend on wavelength.
100
What are the two main types of telescopes?
Refracting and Reflecting
100
Explain the electromagnetic spectrum.
Electromagnetic spectrum is the entire range of all types of electromagnetic radiation, organized by their frequency and wavelength, encompassing everything from low-energy radio waves to high-energy gamma rays

What is the name of the Astronomy professor at UWSP.
Professor Zamfir
200
How do light waves differ from sound waves or water waves?
They do not need a medium to travel through.
200
What is the approximate size of gamma radiation (a wave of light in the gamma ray spectrum)?
Subatomic particle / nucleus of atom
200
What type of telescopes do we use in modern day and why?
Reflecting, because we avoid effects like chromatic abrasion and the size that refracting telescopes need to be.
200
True or False: Do radio waves pass through our atmosphere?
True
200
What is Mr. Hackett's favorite hobby?
Fishing
300
Which type of light travels the fastest?
All light travels at the same speed.
300
What type of spectra is pictured here?
Emission Spectra
300
What type of telescope is pictured here?
300
Why do some wavelengths of light not pass through our atmosphere?
Our earth has a magnetosphere that blocks high energy light waves from entering our atmosphere.
300
What is one of Mr. Hackett's siblings name?
Isaac or Avery
400
Which color of wave has the highest energy?
Pink
400
What can we tell about the stars spectra that is pictured at the bottom compared to the normal sodium spectral lines on top?
The star is "blueshifted" which means the star is moving towards us.
400
Calculate the magnification of a telescope that has a Focal Length of the objective lens of 500mm and an eye piece of 50mm.
10x is the magnification.

What is Mr. Hackett's favorite sweet treat? Extra points for the specifics.
Donut, Apple fritter.
500
How fast does light travel in Km per second?
300,000 Km/s
500
Explain the doppler effect?
Doppler effect refers to the perceived change in frequency of a wave that is emitted from a source that is moving away or toward an object.
500
What is the name of the telescope that we have in space to capture gamma radiation?
Compton Gamma Ray Observatory
500
Explain how Interferometry works.
Combine information from several widely spread radio telescopes as if they came from a single dish.

What is the company Mr. Hackett worked for before teaching?
Cru
