Resumo de Recurso
Waves - Physics
Progressive Waves
Mechanical
Requires a medium to travel through (e.g. Sound, surface water waves, waves on a string, earthquake waves etc.)
Electromagnetic
Radio waves
All EM waves are transverse in nature
Visible light
Microwaves
Transverse
Oscillations are perpendicular to the direction of wave propagation
Examples include waves on a string, microwaves, earthquake S waves
Longitudinal
Oscillations are parallel to the direction of wave propagation
Examples include sound waves and earthquake P waves
Definitions
Displacement (x) of a particle is its distance and direction from its equilibrium position
Amplitude (A) is the maximum displacement from the equilibrium position
Frequency is the number of oscillations passing a point in the wave per second
Period (T) is the time for one whole oscillation (one cycle)
Phase difference is the fraction of a cycle difference between the vibrations of two particles
Wavelength is the least distance between adjacent which are in phase
Useful equations
Phase difference = (distance between two points on the wave / wavelength) x 360 (for a displacement distance graph)
Phase difference = (time between the two points on the wave/time period) x 360 (for a displacement-time graph)
Wave speed = frequency x wavelength
Refractive index = speed of light in a vacuum / speed of light in the medium
Refraction
When waves pass from low to high refractive index (n < n'), they slow down and are refracted towards the normal
When waves pass from high to low refractive index (n > n'), they speed up and are refracted away from the normal
Snell's law: n1 sin
