Relationships
Directly Proportional (M)
what kind of relationship do amplitude and energy have in a mechanical wave?
A wave that travels perpendicular to the direction of disturbance
What is a transverse wave?
The bending of waves around obstacles and openings
What is diffraction?
The distance between 2 crests or troughs of a wave
What is wavelength?
A change in frequency due to motion between source and listener
What is the Doppler Effect?
Inverse
What kind of relationship do energy and wavelength have in an EM wave?
A wave that travels parallel to the direction of the disturbance
What is a longitudinal wave?
The bending of light/other waves as they pass from one object to another
What is refraction?
The max displacement of a wave from its rest position
What is amplitude?
A siren sounds higher when approaching and lower when receding
How does the Doppler Effect affect sound waves?
Directly Proportional (EM)
What kind of relationship do energy and frequency have in an EM wave?
A wave that requires mediums to travel
What is a mechanical wave?
The change in direction of a wave as it meets a boundary it cannot go through
What is reflection?
The speed at which a wave travels through a medium
What is wave speed?
Light from a star will appear blue-shifted when moving closer and red-shifted when moving away
How does the Doppler Effect affect light waves?
Liquids and gases
Which media does sound travel slower through?
A wave that doesn't require mediums to travel
What is an electromagnetic wave?
Two or more waves meet and affect each other's amplitude, which often results in a new wave
What is interference?
The number of waves passing by per second
What is frequency?
There are shorter wavelengths and higher frequency
What happens when a blue-shift occurs?
A vacuum
Which medium does light travel the fastest through?
Radio waves, gamma rays and microwaves
What are some examples of EM waves?
Waves can either combine and form a bigger wave, or they can cancel each other out and form a smaller wave
What happens during constructive and destructive interference?
v = frequency times wavelength
What is the formula for wave speed?
There are longer wavelengths and lower frequencies
What happens when a red shift occurs?
