Viewing Radio Waves

In this interactive activity adapted from NASA, learn about radio waves and how astronomers use them to study objects in space. Understand how radio waves are part of the electromagnetic spectrum and explore how the frequency, wavelength, and speed of a wave are related to each other. Investigate the differences between radio waves and sound waves and learn how astronomers use radio waves to create images. Compare optical and radio images of galaxies and nebulas.

This media asset was adapted from Mission Science: "Radio Waves"/ NASA.
