2 types of Waves

​

Transverse Wave:
I​n this example, the wave moves to the right and a particle on the wave moves up and down or perpendicular.

Longitudinal Wave:
I​n this example, the wave moves to the right and a particle on the wave moves back and forth in the same direction or parallel.

Light Wave

​

​Light does not require a medium in order to transport energy. Space is considered a vacuum since it is not composed of any matter.

What affects the speed of sound?

• Sound needs a medium(material to travel through)

• The type of medium that the sound travels through, affects how quickly it can travel.

• Sound travels fastest through solids because solids are denser than liquids or gases

Multiple Choice

Which of the following materials would sound travel fastest through?

• a wooden desk

• a sponge

• a beaker of water

• the air in the room

Multiple Choice

Why can't sound travel in space?

• Sound needs a medium and cannot travel in a vacuum.

• Sound cannot travel in a medium.

• Sound can not travel where there is no light.

• The distance in space is just too far.

Multiple Choice

If a sound waves moves from a gas to a liquid, the sound wave will

• speed up

• slow down

• not change speed

Maximum distance the particles of the medium carrying a wave move away from their rest position​(Height)​

** In sound waves, amplitude refers to the volume. High amplitude, high volume or loud and vice versa​.

​

Amplitude​

​

The number of complete waves that pass a given point in a second.

** In sound waves, the frequency refers to pitch. Higher frequency, higher pitch and vice versa

​

​​Frequency

​

Distance between two corresponding points on a wave.

Crest-Crest/Trough-Trough

Compression-Compression/Rarefaction-Rarefaction​

​​Wavelength

​***Frequency and wavelength are inversely related. As one increases, the other decreases.***
