Only a few solar system objects are close enough to be explored with probes. . Astronomers rely on electromagnetic waves to gain information about the universe.. Section 1: . The Milky Way Galaxy. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. What is the size and shape of our galaxy?. What are the different kinds of variable stars?. Electromagnetic Radiation. Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . 1. The Electromagnetic Spectrum.

Electromagnetic energy. . What do X­rays, light, microwaves, radio waves, and infrared have in common? . . EM Radiation. Radiation can be described as the movement of energy through space. . There are many different sources of radiation that vary by intensity. . Waves. What is a wave?. A wave is a disturbance that travels from one location to another location. The traveling disturbance in a wave is carrying energy (NOT matter). Waves that require a medium to travel through are . March 25. June 18. September 26.

The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
