Previous: Introduction to Waves
We experience many different types of waves in our daily lives:
light, radio waves, breaking waves at the beach, sound of cars
passing by on roads, etc. What all of these different types of
waves have in common is that they PROPAGATE, or move from one
place to another. We can also subdivide all waves into two major
Electromagnetic waves, such as light and radio waves. These waves
are governed by Maxwell's equations that you may have seen in a physics
class. This course will not discuss electromagnetic waves.
Mechanical waves, such as sound waves or the waves you see on the water surface.
Waves inside plates or rods are also mechanical waves.
Mechanical waves are central to noise control engineering, and are the focus
of this unit.
