Physics Flashcards
Transverse waves
Vibrations occur at right angles/perpendicular
Amplitude
Maximum distance from rest to peak
What do all sounds require?
A medium to travel through (i.e particles)
What can’t sounds pass through?
Vacuums (i.e space)
What are sounds created by?
Vibrating objects
In what state of matter does sound travel fastest in?
Solids
How can sound travel faster?
Closer the particles, faster the sound
Wavelength
Distance between two corresponding points or neighbouring waves
Pitch
How high or lough a sound is
Peak
Highest point
Control variable
What stays the same
Independent variable
What changes
Dependent variable
What is measured
Formula/equation for speed
Speed= Distance travelled (metres)/Time taken (seconds)
Unit of measurement for speed
M/s ( metres per second)
Equation for distance
Speed x Time
Equation for time
Distance/speed
Frequency
The number of waves that pass a given point in one second
Loudness
How loud or quiet something is
Longitudinal Waves
Vibrations occur in the same direction as the direction of energy transfer
What do all types of waves have?
Frequency
What is the unit for frequency?
Hz (Hertz)
What does 10 hz mean, for example?
Ten vibrations per second
Inversely proportional
When one variable doubles, the other halves.
Does the frequency affect the amplitude?
No
Superposition
What happens after two waves meet after approaching each other
Convection
Heat rises and as it does it cools down, continues this cycle
Thermal Equilibrium
When everything is the same temp.
Conduction
Heat transfer of diff particle
