Unit: Sound and Light
Lesson 1: What are Waves?
Essential Questions:1.) What forms mechanical waves?
2.) What are the types of mechanical waves?
Characteristics of Waves
A disturbance that Wavetransfers energy
The material through Mediumwhich a wave travels
Waves that travel Mechanical wavethrough a medium
What is the medium?
Water
Air
Rope
A back-and-forth or Vibrationup-and-down motion
Moving objects have energyThe energy causes the medium to vibrateThe vibration causes a wave
Energy Source
Where does the energy come from?
Medium
What is the medium?
Vibration
What happens when the water vibrates?
Transverse Wave
Movement of the rope
Direction of the wave
Transverse Wave
Crest
Trough
Longitudinal Wave
Movement of the slinky
Direction of the wave
Longitudinal Wave
An area where the coils Compressionare close together
An area where the coils Rarefactionare spread out
Surface Waves
A combination of transverse and longitudinal waves
This wave travels along a surface that separates two mediums
The water moves back and forth
The bottle moves in a circular motion
