Waves Flashcards
What are transverse waves
The oscillations are at 90 degrees perpendicular to the direction of energy transfer
What are longitudinal waves
Oscillations are parallel to the direction of energy transfer
Bother types of waves are _______ waves.
Progressive
What does a progressive wave mean
A wave that transfers energy not matter
Definition of amplitude
The maximum displacement from equilibrium
Definition of wave length
Distance covered in one complete cycle/oscillation
Definition of time period
Time taken for one complete cycle
Definition of frequency and measured in what
Number of oscillations per second : measured in Hz hertz
What is wave speed - frequency - wavelength measured in
S= m/s F=Hz W=m. Wavelength and speed measurement depend on each other (m,cm?)
What is the equation linking distance time and speed
D= s x t
Relationship between frequency and time period
T= 1/F Or F=1/T
Loud sound =
Tall/big amplitude
Quiet sound
Small amplitude
High pitch =
High frequency
Low pitch
Low frequency
