G4 T3 Waves and Information L2 Patterns of Waves
Objective: I can describe how waves can oscillate.

Ham Radio
4
Patterns in Wave Characteristics
Amplitudes, wavelength and frequency of waves follow a pattern
If you observe the properties of part of a wave, you can figure out how the rest of the wave is doing.
One important pattern of waves that the can Oscillates.
5
Oscillates:
Move back and forth between two points.
Some other objects that can oscillates like pendulums and rocking chairs.
6
Wave Period
The amount of times it takes for a wave to complete one back and forth.
7
Remember
Waves with high frequency have shorter wavelength
8
Wave patterns
Objective: I can tell the difference between circular and plane waves.

Wave patterns:
In order for a wave to appear, a disturbance must happen in a medium.
Appear:
To be seen or show up
Different disturabnce cause waves with different patterns.
11
Circular wave:
Disturbance at one point
Waves will spread out in all directions.
Waves look like circles.
Circular waves:
Waves that caused by a disturbance at one single point.
12
plane waves:
For example, if you push the water with your hands, the waves will move in parallel lines.
move in parallel lines
look like stripes
Plane wave:
The wave that is made when a disturbance happens to a line of matter.
