PRESENTATION OUTLINE
What are waves
A wave is a disturbance that transfers energy from place to place.
Transverse
A transverse wave is a wave that moves the medium at right angels to the direction the wave is moving.
Longitudinal
A longitudinal wave is a wave that moves the medium parallel to the direction in which the wave is traveling.
Amplitude
Amplitude is the maximum distance that the particles of the medium carrying the wave more away from their rest position.
Wave length
Wave length is the distant between two corresponding parts of a wave.
Frequency
Frequency is the number of complete waves that pass a given in a certain amount of time.
Speed
The speed of a wave is how far the wave travails in a given length of time.
Reflection
An object or a wave hits a surface through which it cannot pass.
Refraction
The Bending of waves due to a change in speed.
Diffraction
When a wave moves around a barrier or through an opening in a barrier.
Interference
Is the interaction between waves that meet.
Standing waves
Standing waves are waves that appear to stay in one place.
Standing waves
A standing wave appears to stand in one place.
Seismic waves
Seismic waves are
produced from earthquakes.
Two types of seismic waves
There are P waves and S waves
Detecting seismic waves
Scientist can see where the seismic wave are by using a seismograph.
Sound waves
Sound is the disturbance that travels through a medium as a longitudinal wave.
Interactions of sound waves
Sound waves reflect off objects, and diffract through narrow openings and around barriers, and interfere with each other.
What is pitch
Pitch is the sound of how high or low the sound is.
What is loudness
Loudness is a sound on how high low the sound is with decibel.
Electromagnetic waves
Electromagnetic waves are waves that vibrate electric and magnetic fields and move through space and speed of light.
Types of electromagnetic waves
There are electromagnetic radiation.
