Mr. Bradley Waves

A ball floating on the water is a good example of the difference between a wave and ordinary harmonic motion.

Waves carry oscillations from one place to another

When your watching a musician on stage. The voice or instrument creates waves that carry the sound to your ears.

.You dail a cell phone to call a friend. That waves is know as a microwaves moves through a antenna and carries a signal to the person your calling.

Even a cell phone uses waves.

​Some text here about the topic of discussion.

Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.

​Some text here about the topic of discussion.

Longitudinal or compression waves are defined as waves where the particle motion is in the same direction in which the wave is propagating.

​Some text here about the topic of discussion.

Examples of Longitudinal Waves

• Sound waves in air.

• The primary waves of an earthquake.

• Ultrasound.

• The vibration of a spring.

• The fluctuations in a gas.

• The tsunami waves.

How do you determine which way a wave is moving?

For each of the waves use the Right-Hand Rule to determine the missing information. Point the fingers of your right hand in the direction of the electric field, bend them in the direction of the magnetic field, and then your thumb will point in the direction of the wave propagation.

Diffraction

(Noun)

noun

1. the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.

A guitar use the natural frequency of the strings to make the correct notes. Once it is tuned, the A string, when picked, will always vibrate at 440 hertz. This is the LEGENDARY Erine Isley from the group The Isley brothers.
