S8P4 Students will explore the wave nature of sound and electromagnetic radiation a Identify the characteristics of electromagnetic and mechanical waves What are waves Waves carry energy Rhythmic disturbances that carry energy without carrying matter are called waves. some history. (based on D. . Kennefick’s. work). Historical tidbits. 1776: Laplace suggests four mechanisms that could explain secular perturbations of Moon-Earth orbit. One the explanations was a non-instantaneous propagation of gravity, affecting the binary system (abandoned because its speed would be too large to be measurable to explain the effect). . Tamara .

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

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..
