The next slides show images of the SAME region of sky, but using different types of light. The view in VISIBLE LIGHT. INFRARED. RADIO WAVES. RADIO WAVES. GAMMA RAYS. Different types of light give us different information!. . 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. . Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. 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 .
