Studying Space

The electromagnetic spectrum consists of

• all of the colors of light you can see with your eyes.
• all of the different types of electromagnetic waves.
• a band of colors formed when white light passes through a prism.
• the distance between the crest of one wave and the crest of the next wave.

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.

Reflecting telescopes differ from refracting telescopes in having

• no eyepiece lens.
• two large objective lenses.
• a mirror instead of an objective lens.
• one large objective lens.
