Waves

Aim What are they and how do they work

Waves carry energy There are 3 basic types

Mechanical Waves(sound)

Electromagnetic Waves(light)

Matter Waves(atomic particles)

Mechanical Waves

bull Require a medium for the wave to propagatendash Waterndash Soundndash Slinkyndash Bridges

Electromagnetic Waves

bull NO MEDIUM REQUIRED

bull Travel at the speed of light (299792458ms)ndash Light

ndash Radio x-rays

ndash microwave

Matter Waves

bull Electrons and other particles show wave-like behavior

bull This is some freaky stuff we will study in Quantum Physics

Mechanical Waves

bull Are classified by the way that they move (displace) the medium they are in

bull The three types of mechanical waves arendash Transversendash Longitudinalndash Surface

Transverse Waves(light)bull Causes the medium

in which the wave moves through to move perpendicularly to the direction the wave is traveling

bull Light waves travel in straight lines and do not need a medium to travel

Longitudinal Waves(sound)

bull Medium moves in the same direction as the wave

bull Particles get compressed

bull Sound waves travel in all directions

Surface waves

bull Exhibit characteristics of both Transverse and longitudinal waves

bull Water wave

Keep in mind

bull Even though particles in the medium of a mechanical wave move in response to the wave they do not move along with the wave

bull The wave only transfers energy

It happens to be a very effective means of transferring ENERGY

Transmission

Absorption

Reflection

Vocabulary terms common to all waves

Pulse

bull Single disturbance that travels through a medium

Periodic Wave

bull A series of pulses moving in a regular repeating manner

Things That All Waves Have in Common

Crest and Trough

bull The crest is the high point

bull The trough is the low point

AmplitudeThe amplitude of a

wave is the distance from a crest to where the wave is at equilibrium The amplitude is used to measure the energy transferred by the wave The bigger the distance the greater the energy transferred

Period (T) (in seconds)bull How long it takes one cycle of a

wave to repeat itself

Frequency (f) (in Hertz Hz)bull The amount of wave cycles per

second

bull f = 1T therefore T = 1f

bull Find the frequency of a wave with a period of 05 seconds

Wavelength (λ) (in meters)

bull Distance between repeating parts of a wave

bull Crest to crest bull Trough to trough

Phase

bull Points on successive wave cycles of a periodic wave that are displaced by the same amount and in the same direction (away or towards) equilibrium are said to be in phase

Polarization of a Wave

Any transverse wave can be polarized

Standing Waves

bull Wave appears to be standing still as the result of identical waves moving in opposite directions

Nodes Antinodes

Speed of a Wavebull Can be found by

bull v = λT = meterssecondsbull therefore

bull v = f λbull The speed of any particular wave

depends ONLY on the medium it is in

Wave InteractionSuperposition

When Two Waves Meet Two Things Can Happen

Constructive Interference

bull When the peak of one wave matches up with the peak of another wave

bull The new amplitude is the sum of the amplitudes of both waves

Destructive Interference

bull When the crest of one wave and the trough of another line up you have total destructive interference

bull The level of destructive interference depends on how well they line up

Both Types of InterferenceAreas of maximum constructive interference

The Telltale Sign of a Wave

bull When this experiment is performed and the result is the appearance of these ldquomaximardquo you know that the thing in question moves as a wave

bull It turns out that this works for light too

bull This lead people to believe light travels as a wave

Page 8: Waves Aim: What are they and how do they work?. Waves carry energy! There are 3 basic types. Mechanical Waves(sound) Electromagnetic Waves(light) Matter.

Longitudinal Waves(sound)

bull Medium moves in the same direction as the wave

bull Particles get compressed

bull Sound waves travel in all directions

Surface waves

bull Exhibit characteristics of both Transverse and longitudinal waves

bull Water wave

Keep in mind

bull Even though particles in the medium of a mechanical wave move in response to the wave they do not move along with the wave

bull The wave only transfers energy

It happens to be a very effective means of transferring ENERGY

Vocabulary terms common to all waves

Pulse

bull Single disturbance that travels through a medium

Periodic Wave

bull A series of pulses moving in a regular repeating manner

Things That All Waves Have in Common

Crest and Trough

bull The crest is the high point

bull The trough is the low point

AmplitudeThe amplitude of a

wave is the distance from a crest to where the wave is at equilibrium The amplitude is used to measure the energy transferred by the wave The bigger the distance the greater the energy transferred

Period (T) (in seconds)bull How long it takes one cycle of a

wave to repeat itself

Frequency (f) (in Hertz Hz)bull The amount of wave cycles per

second

bull f = 1T therefore T = 1f

bull Find the frequency of a wave with a period of 05 seconds

Wavelength (λ) (in meters)

bull Distance between repeating parts of a wave

bull Crest to crest bull Trough to trough

Phase

bull Points on successive wave cycles of a periodic wave that are displaced by the same amount and in the same direction (away or towards) equilibrium are said to be in phase

Polarization of a Wave

Any transverse wave can be polarized

Standing Waves

bull Wave appears to be standing still as the result of identical waves moving in opposite directions

Nodes Antinodes

Speed of a Wavebull Can be found by

bull v = λT = meterssecondsbull therefore

bull v = f λbull The speed of any particular wave

depends ONLY on the medium it is in

Wave InteractionSuperposition

When Two Waves Meet Two Things Can Happen

Constructive Interference

bull When the peak of one wave matches up with the peak of another wave

bull The new amplitude is the sum of the amplitudes of both waves

Destructive Interference

bull When the crest of one wave and the trough of another line up you have total destructive interference

bull The level of destructive interference depends on how well they line up

Both Types of InterferenceAreas of maximum constructive interference

The Telltale Sign of a Wave

bull When this experiment is performed and the result is the appearance of these ldquomaximardquo you know that the thing in question moves as a wave

bull It turns out that this works for light too

bull This lead people to believe light travels as a wave
