Term
What are Waves?
Definition
Transfering energy from one place to another
Term
What is a Transverse wave?
Definition
When vibration causes the wave to move perpendicular to the direction of energy transfer. and it moves in an up and down motion
Term
What is a Longitudinal Wave?
Definition
When the vibration moves in the same diraction as the energy transfered.
Term
what is the wave equation?
Definition
wavespeed(m/s)= frequency(Hz)x wavelength(m)
Term
How do you find the time period?
Definition
T = 1/frequency
Term
How do you fine speed?
Definition
speed = frequency x wavelength
Term
What are different types of transverse waves?
Definition
Water waves, gamma, x-ray, ultra violet, light, infra red, microwaves, radio waves
Term
What are different types of Longitudinal Waves?
Definition
Sound, and Ultra sound
Term
What is Amplitude (a)
Definition
Height of a wave noting the energy it carries, measured in meters
Term
What is waveleaght (upside down y)
Definition
distance between two successive points that are in phase. measured in meters
Term
What is Frequency? (Hz)
Definition
how many waves pass each second. measured in hertz
Term
What is Time period? (T)
Definition
Time taken for one complete wave to pass. measured in seconds
Term
What is wave speed? (v~)
Definition
how fast a wave travels. measured in meters per second (m/s)
Term
