Waves & Properties of Waves

​Waves

​Waves are repeated disturbance that transfers only energy but not matter

​

​

​* There are 2 catetogries of waves

​1. Mechanical Waves

​2. Electromagnetic Waves

​Mechanical waves vs. Electromagnetic Waves

​Mechanical Waves

:​Requires a medium to travel through

​Transverse Waves

​Moves up and down at right angles perpendicular to the direction of the wave. Ex: Rope waves, Ocean waves, & Stadium Waves

​

​Longitudinal/Compressional Wave

​moves back and forth or side to side parallel to the direction of the wave

Ex: Sound waves, Slinky Toy, & Primary Waves​

​

​

​Electromagnetic Waves

• ​Can travel through empty space and a medium.

• Are transverse waves only, therefore they only move up and down

​Properties of Waves

​Include

​

​1. Frequency

​2. Wavelength

​3. Amplitude

​4. Wave Speed

​Frequency

• Is a measure of how many waves pass a certain pint in a certain amount of time.

• ​The unit for Frequency is Hertz.

• ​High frequency waves are closer together.

• ​Low frequency waves are farther apart.

WHAT IS THE FREQUENCY OF THE WAVES?

​

​AMPLITUDE (THE HEIGHT OF THE WAVE)

​is a measure of the distance from the rest postion to the crest or from the rest postion to the trough. FINDING THE AMPLITUDE OF THE WAVE.

​WAVELENGTH

​Of a Transverse Wave: is a measure of the distance from the crest to crest or trough to trough.

​

​Of a Longitudinal/Compressional Wave: the distance from rarefaction to rarefaction or compression to compression.

​Finding the wavelength

​What is the wavelength?

​Relationship between frequency, wavelength, and energy.

• ​Higher frequency has high energy and shorter wavelength.

• ​Low frequency has low energy and longer wavelength.

• ​As frequency increases, wavelength decreases.

• ​To increase the energy of a wave, the amplitude and frequency must be increased.
