Telescopes

What is the major drawback of radio telescopes?

• They can only be used at certain hours of the day

• They are too small

• They have a low resolution

• They have complex mirror systems

Modern telescopes are reflecting because: (Choose all that apply)

• Lenses are difficult to manufacture

• Lenses are heavy and fragile

• lenses absorb light that passes through them

• Lenses require only 1 perfect surface

Modern telescopes don't use film to capture images, instead they use:

• CCDs

• USBs

• HDDs

• CD-ROMs

Which of these can solve the issue of atmospheric blurring? (choose all that apply)

• Active Optics

• Adaptive Optics

• Putting a telescope in space

• Putting a telescope underground

Which of these is a process that is unique to radio telescopes?

• Spectrometry

• Inferferometry

• Photometry

• Photography

Which of these light types cannot be captured by a telescope?

• Radio waves

• Microwaves

• Ultraviolet

• All of them can be captured

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.
