Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . College Physics Chapter 24 ELECTROMAGNETIC WAVES PowerPoint Image Slideshow Figure 24.1 Human eyes detect these orange “sea goldie ” fish swimming over a coral reef in the blue waters of the Gulf of Gravitational Wave Bonus). 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!. Light, microwave, x-ray, TV, and cell phone transmission are all kinds of . electromagnetic waves. .. Electromagnetic waves are a group of energy waves that are mostly invisible and can travel through empty space.. 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 . 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..
