what is a
pulse ?
A
single disturbance Complete .
cycle of a
vibrating system .
↳ aka oscillation
Transverse Pulse
Travels I of
Single disturbance .
to direction disturbance .
Pulse Length
Distance between first displaced particle in pulse to the last
↳ it indicates pulse length .
measured in Cms
Amplitude
Max displacement of particles of the medium from rest position
↳ Amplitude CA) : Measured in meters
wave
Regular disturbance that is repeated
Wavelength between

Distance 2
adjacent points in phase
Transverse Wave
of
Vibrating source moves in direction I to direction
propagation .
Dif .
between wave and Pulse
Wave
Pulse
is caused
by regular vibrations
is caused
by single disturbance
, Crest and
Troughs
Crest :
Max position above rest position
Trough :
Minimum position below rest position .
In Phase and Out Phase
Particles at crests are in
phase
Particles at crest and
trough are out phase with one another
Relationship Between Period and
Frequency
Period and
Frequency are related
↳ Period of
is the inverse
frequency
T =
ft ( seconds) T :
time taken to complete one
cycle .
Frequency is the inverse of period
f = ¥ ( Hz) f :
num waves that pass a fixed point in a
certain amount of time .
