What is a wave?
|
A disturbance that transmits energy through matter or space.
|
|
Calculate the speed of a wave.
|
Wavelength/period
|
|
What do waves transfer?
|
Energy
|
|
What is the difference between a mechanical wave and an electromagnetic wave?
|
Electromagnetic- does not require a medium, disturbance in electric and magnetic fields.
|
|
What is the connection between vibrations and transformations of energy?
|
Simple harmonic motion- faces that push in opposite directions
|
|
How do particles move in transverse and longitudinal waves?
|
Transverse- perpendicular , longitudinal- parallel
|
|
How do particles move in a surface wave?
|
Circles
|
|
How can you measure the amount of particle vibration?
|
Period
|
|
How can you determine wave speed?
|
Frequency x wavelength
|
|
What does the speed of a wave depend on?
|
Medium
|
|
What do you know about ALL electromagnetic waves as they travel through empty space?
|
They travel at the same speed
|
|
What is the relationship between frequency and pitch?
|
Pitch is determined by frequency
|
|
Understand the Doppler effect?
|
An observed change in frequency of a wave when the source/observer is moving
|
|
Understand how waves behave. Reflection, refraction, and diffraction.
|
Reflection- the bouncing back of a wave when it meets a surface, diffraction- the bending of a wave as it passes an edge or opening, refraction- the bending of waves as they pass from one medium to another
|
|
What happens when two waves interfere?
|
Constructive- combining of waves where it is bigger than the original, destructive- resulting wave is smaller
