We first explore mechanical waves, characterized by forces and displace-ments.We then come to electromagnetic waves, where no material object moves and only the electric and magnetic fields change as they chase each other through empty space. 11.1 What is a wave? Different kinds of waves. Think of a quiet lake.
Explain the difference between Electromagnetic and Mechanical Waves. Identify examples of each of the waves. Create their own body waves to simulate the different waves. Time Required: 75 minutes. Materials Needed: Teacher computer with internet access. Projector/Smartboard. 1 computer/laptop/iPad per student with internet access.
1 Types of Mechanical Waves. waves that travel within some material called a medium. Waves play an important role in how. we perceive our physical world (e.g., sight and sound). Not all waves are mechanical, (e.g., electromagnetic waves); however, the terminology and concepts w.
What are electromagnetic waves? How are they created, and how do they travel? How can we understand and organize their widely varying properties? What is their relationship to electric and magnetic effects? These and other questions will be explored. Misconception Alert: Sound Waves vs. Radio Waves.
13.4 Plane Electromagnetic Waves. To examine the properties of the electromagnetic waves, let’s consider for simplicity an electromagnetic wave propagating in the +x-direction, with the electric field E pointing in the +y-direction and the magnetic field B in the +z-direction, as shown in Figure 13.4.1 below.
The variety of possible EM waves is virtually unlimited, since we can just keep cranking up the frequency, but there are only a handful of types of EM waves or radiation that we name.
