Things we use that use waves
|
|
|
True or False
Energy can be carried by a wave |
TRUE
|
|
|
|
How does a "wave" travel?
|
It uses energy.
|
|
|
|
A ___________ is a substance through which a wave can travel.
|
WHAT IS A "MEDIUM"
|
|
|
|
A medium can be in what three forms?
|
SOLID
LIQUID GAS |
|
|
|
What type of waves require a medium?
|
SOUND WAVES
|
|
|
|
________ is the medium of which sound waves travel in.
|
AIR
|
|
|
|
Sound waves can travel through which medium ( media)
|
SOUND
LIQUID GAS |
|
|
|
How do sound waves travel?
|
As Vibrations
|
|
|
|
TRUE OR FALSE
Sound can be heard with out a medium |
FALSE
You will not hear the sound if there is no particle to vibrate against. |
|
|
|
Waves that need a medium (media) are called___________ waves
|
MECHANICAL
|
|
|
|
Describe how a longitiudial wave travels.
|
The particles of the medium vibrate back and forth the path that the wave travels.
|
|
|
|
What type of wave is a longitudinal wave?
|
SOUND WAVE
|
|
|
|
A ____________ wave is when there is a boundary of two media.
|
TRANSVERSE WAVE
|
|
|
|
Describe how transverse waves work.
|
Waves move in circles verses up and down.
|
|
|
|
How do transverse waves differ from longitudinal waves.
|
Transverse waves move across to the direction of the wave. Longitudinal Waves move back and forth like a spring
|
|
|
|
Why could we not hear an explosion on earth?
|
Beause there is no air, gas, or water to have the sound travel in.
|
|
|
|
What kind of waves do not require a media.
|
Electromagnetic Waves
|
|
|
|
Give some examples of electromagnetic waves./
|
X-Ray
Microwave TV Signal Radio Signal |
|
|
|
The _________ of a wave it the maximum distance the wave vibrates
|
AMPLITUDE
|
|
|
|
The larger the amplituede is the _________ the wave is.
|
TALLER
|
|
|
|
Larger amplitude means (larger) or (smaller) amount of energy
|
LARGER
|
|
|
|
Give an example with a jump rope.
|
You have to shake the rope harder to make the waves "larger" verses less energy to make "smaller" waves
|
|
|
|
The _______ is the distance between two adjacent crests or compressions is a series of waves.
|
WAVELENGTH
|
|
|
|
True or False
All wave lengths will be equal from one point to the next. |
TRUE
If you measure at any given wavepoint. the measurement will be the same for any given wave. |
|
|
|
The number of waves produced in a given amount of time is called the ________.
|
FREQUENCY
|
|
|
|
How is frequency measured?
|
Counting the number of crests
|
|
|
|
The __________ of a wave is the maximum distance the wave vibrates from its resting position.
DRAW A WAVE AND SHOW THE AMPLITUDE AND WAVE LENGTH |
AMPLITUDE
|
|
|
|
The speed in which a wave travels is the ___________.
|
WAVE SPEED
|
|
|
|
How can wave speed be calculated?
|
Wavelength x Frequency = SPEED
|
|
|
|
What is the speed of the following
Frequence (f) = 3/second Wavelength = 0.5m |
.05M X 3hX = 1.5 M/S
|
|
|
|
_____________ is the bending of a wave as it passes at an angle from one medium to another.
|
REFRACTION
|
|
|
|
Give an example of refraction:
|
The speed changes when an object is falling from air to water. It will travel faster through air, then slow down as it travels through water,
|
|
|
|
_______________ is the bending of waves around a barrier.
|
DIFFRACTION
|
|
|
|
Why can you hear sound through a barrier better than see light through the same barrier.
|
Sound waves are much longer than light waves.
|
|
|
|
What is interference
|
When two waves meet in the same space
|
|
|
|
Describe an incident of interference with musical instruments.
What happens with the sound |
Sound Waves are traveling all at the same time from each instrument. When together, it creates a louder sound becasue they overlap
|
|
|
|
What happens when a wave is refracted?
|
The speed changes. This causes the wave to bend.
|
|
|
|
A ____________ wave is a wave that forms a stationary pattern.
|
STANDING WAVE
|
|
|
|
Describe what happens in a standing wave. Is it really still?
|
Waves are traveling in two directions making it appear that they are still. Yet they are really moving.
|
|
|
|
What is resonance and when does it occur?
|
When an object is vibrating at or near the frequency of another object.
The Xylophone is an example. The hitting with the mallot causes a vibration in the keys and the air. |
|
|
|
How can resonance be destructive?
|
A Bridge:
You have vibratin from the cars and other elements like wind which cause a bigger vibration, which can cause a bridge to break |
|
|
|
As the wavelength increases, the frequency _________________.
|
Decreases
