Another name for light bending is ....

• Reflaction
• Absorbing

Which of the following does the radiation from a star tell us

• temperature
• velocity
• composition
• all of these

light emitted from an object moving towards you will have its wavelength shorted and will be considered

• red shiffted
• blue shiffted

Both reflecting and refracting telescopes are designed to

• break visible light into colors of the spectrum.
• separate visible light from ultraviolet and radio waves.
• gather and focus visible light.
• work better with short-wavelength radiation.

Why are many large optical telescopes located on mountains?

• to be closer to the stars
• to be above part of the atmosphere
• because it is easier to build telescopes on mountains
• to be closer to city lights

A device that detects radio waves from objects in space is called a(n)

• radio telescope.
• reflecting telescope.
• refracting telescope.
• electromagnetic telescope.

A spectrograph breaks the light from an object into a(n) ____________, or range of different colors, and produces an image of it.

• spectrum
• spectragraph
• visible light
• prism

Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies
• They have very large optical lenses
• So its images arent distorted by Earth's atmosphere 
• So it can be operated by astronauts
