Waves And Pulses Flashcards
Pulse
Single disturbance in a wave the moves from one direction to another
Transverse pulse
Occurs when particles move perpendicular to the sources direction
Frequency
F , cycles per second measures in hertz Hz
Period
T seconds per cycle measured in seconds
Constructive interference
Two pulses meet at the same point and the amplitudes are then added together
Interference
Two or more pulses are at th same point in the same place and at the same time
Destructive interference
When two pulses or waves meet at the same point in the same medium they superimpose on each other to creat a lower amplitude
amplitude
Maxim displacement of a particle in a medium Ym
Phase
Is related to the particles and there position on the medium
Wave length
Shortest point between two points that are in phase
Longitudinal wave
Disturbance of medium is proportionate to the propagation direction
! )) )) ))
Condensation / compression
)))) when pressure is created through a medium
Peak
Rarefaction
Space between compression
Trough
Angle of incident
Angle that sound hits hard surface is equal to the trajectory
Reverberation
Echoed
