Waves - Coggle Diagram
Waves
Sound
Sound is a wave
Sound is a type of a mechanical wave
Sound is a wave that is produced by cibrating object and travels through matter
Vibration is a rapid, back0-and-forth motin
How sound waves are produced
How sound waves are detected
Sound waves vibrate particles
Vacume is empty space
The speed of sound dependent on its medium
The effect of the material
The effect of temperature
Frequency determines pitch
Pitch depends on the frequency of a sound wave
High and low frequencies
A hertz is one complete wave per second
Ultrasound is a sound wave in the range above 20000 hertz
Natural frequenceis
resonance is the strengthening of a sound wave
Sound quality
The motion of the source of a sound affects its pitch
The Doppler effect
Doppler effect is the change perceived pitch that occurs when the source or the receiver of a sound is moving
Frequency annd pitch
Intensity determines loudness
Intensity develops on the amplitude of a sound wave
The intensity of a sound is the amountt of energyy its sound wave has
Decibel is a unit used to measure sound intesity
The intensity of a sond can mbe cotrolled
Amplification
Amplification is the increasing strength of an electrical signal
Acoustitics
Acoustics is the scientific study of sound
Intense sound can damage hearing
Sound has many uses
Ultrasound wave are used to detect objects
Echolocation
Echolocatin is sending ultrasund waves and interpreting the returning sound echos
Sonar
Instruments that us echolocation to l locate objects are sonar
Medical uses of ultrasound
Sound waves can produce music
Sound can be recorded and reproduced
The telephone
Rcorded sound
Waves Transfer Energy
A Wave is a disturbance
Materials and waves
Medium is any substance that a Wave moves trhough
Mechanical waves are waves that transfer energy through matter
Forces and Waves
A Wave is a disturbance that transfers energy to another
Energy and Waves
Waves can be cassified by how they move
Transverse Waves
In a transverse wave, the direction in which the wave travels is perpendicular, or at right angles, to the direction of thee disturbance
Longitudinal waves
In a longitudinal wave, the wave travels in the same direction as the disturbance
Waves have measureable properties
Waves have amplitude, wavelength, and frequency
Measuing wave properties
Crest is the highest point of a wave
A trough is the lowest point of a wave
Wavelength is the distance between each crest
Amplitude is the distance from the crest to the line through the middle of the wave
Frequency is the number of waves passing through a fixed point in a certain amount of time.
How frequency and wavelength are created
Graphingg wave properties
Wave speed can be measured
Speed = wavelength * frequency
Waves behave in predictable ways
Waves interact with materials
Reflection
Reflection is the bouncing back of a wave after it strikes a barrier
Refrraction
Refractino is the bending of a wave as it enters a new medium at an angle other than 90 degrees
Diffraction
Diffraction is the spreading out of waves through an opening or around the edge of an obsitcal
Waves interact with other waves
Interference is the meeting annd combining of waves
Waves adding together
Waves canceling eacthotther out
