PPT-Electromagnetic Waves

Physics 4 Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Maxwells Equations Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Maxwells equations summarize the relationships between electric and magnetic fields A major consequence of these equations is that an accelerating charge will produce electromagnetic radiation.

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!. . 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. . 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..
