• radio waves

• x-ray

• gamma rays

NGSS.HS-PS4-3

NGSS.HS-PS4-4

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.

NGSS.MS-PS4-2

Why do we use the entire electromagnetic spectrum to study space?

• Because the visible spectrum is such a small part of light we are missing out by not doing so.

• So we can determine the direction galaxies are moving

• So we can understand the nature of time.

• So we can see the composition of galaxies
