Mr. Bradley's Waves lesson

In this section you will learn about water waves, sound waves, and light waves.

Why learn about waves?

A ball floating on the water is a good example of the difference between a wave and ordinary harmonic motion. If you poke a ball, it moves up and down. The oscillating ball creates a wave on the surface of the water that spreads outward, carrying the oscillation to other places.

​

We use waves to carry information and energy over great distances.
The sound wave that travels through the air carries information about the vibration of the string from the instruments to your ear. Your ear hears the vibration of the string from the instrument to your car. Your ears hears the vibrations as music.

-The stoplight that you see with your eyes is a wave.

-The sound that you hear are waves.

-The ripples in a puddle of water are waves to.

Waves are around us

Have a nice day. Happy teaching!

Transverse Waves

Longitudinal waves are the waves where the displacement of the medium is in the same direction as the direction of the travel of the wave.

What is the definition of frequency in waves?

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
