Study Notes

General Characteristics of Waves

Waves transport energy without the transport of matter.
Energy movement occurs via a disturbance originating from a source.
Common examples include ocean waves, ripples from raindrops, and sound waves from musical instruments.

Types of Waves

Mechanical waves involve oscillation of material particles, e.g., waves in ropes, strings, water, and air.
Electromagnetic waves propagate through oscillations of electric and magnetic fields, to be studied later.

Mechanism of Energy Transport

Waves are generated through oscillations in vibrating bodies.
Propagation involves collective oscillation of many particles, rather than individual particle motion.
The effect of collective motion can be visualized, such as black and white images made up of closely spaced dots.

Progressive Waves

Progressive waves, such as ripples produced by dropping a pebble in water, are characterized by their ability to carry energy across a medium.
