Travelling waves
component of waves
wavelength
shortest distance between 2 points in phase
frequency, f
number of oscillation per unit time
period, T
time taken to complete one cycle
amplitude, A
maximum displacement
types of waves
transverse wave
definition
source that produce the wave which vibrates perpendicular to the direction of waves travels
longitudinal wave
definition
direction of pulse is parallel to the direction of a wave travel
types of graph
displacement-time graph
definition
displacement of particle for continuous time
graph
displacement-distance graph
definition
displacement of many particle at one time
graph
consist of
mechanical wave: needs medium to propagate
electromagnetic wave: can travels in vacuum
characteristics of EM waves
v = c = speed of light
electric and magnetic field perpendicular to each other
transverse waves
amplitude
wave's maximum electric field strength
sequence
radio, tv, microwave, infrared, visible light, UV, x-ray, gamma (from lower to higher frequency @ from higher to lower frequency)
