Unit 5&6: Wave Properties and Behaviors Flashcards
The highest point on a wave.
Crest
The lowest point on a wave.
Trough
The measure of the amount of energy it carries.
Amplitude
The distance from the crest or trough to the resting point.
wavelength
A measure of the number of waves that pass a point in a given amount of time.
Frequency
What is the definition of a wave?
Transfer of Energy from one location to anthor
What are the 2 main types of waves?
Electromagnetic and Mechical
What kind of wave needs a medium to travel?
Mechical
What is the definition of a medium?
Matter through which the wave travels
How do the particles of a medium move when a wave passes through them?
As particles vibrate, they pass the energy of the disturbance from one particle to the next which then passes energy to the particles next to them.
Which wave can move through empty space?
Electromagnetic
An electromagnetic wave can only travel as what wave?
Transverse
How does the medium of a transverse wave move in reference to the direction of the energy?
Particles of the medium move perpendicular to the direction of the wave.
How does the medium of a longitudinal wave move in reference to the direction of energy?
Moves back and forth in the same direction as the wave travels.
Electromagnetic waves are waves that consist of vibrating _________ and _________________ particles.
Electric and Magnetic field
What are the 4 main wave interactions/behaviors?
Absorption, Reflection, Refraction and Transmission
If a wave hits a mirror at a 60-degree angle, what degree of angle does the wave bounce off of the mirror?
60
Refraction occurs because a wave goes from one _______ to another.
Medium
Mediums with different states of matter have different ________, which causes the speed of the wave to speed up or ________ down.
Densities, Slow
What is Reflection?
When a wave strike off an object and bounces off
What is Refraction?
When waves bend as they enter a new medium at an angle
What is absorption?
When waves don’t move through or reflect off of a medium. The waves are absorbed and the energy is TRANSFERED into the medium.
What is transmission?
Some waves have the ability to pass through a medium with little change to the wave using a property, called transmission
Describe what a Longtudienial wave looks like.
Like a Slinky
Describe what a Transverse wave looks like.
Like a wave
Provide a real-life example of the wave behaviors (ANSWERS WILL VARY!)
Reflection- Light shining off of a mirror
Refraction- Pencil in water
Absorption- Extreme heat on Pavement
Transmission- Cell phone signals coming through your walls to your phone.
