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
 what does Opaque mean?
Definition
 does not let light thought
Term
 what does transparnet mean?
Definition
 it allows light thought
