![]() Rememebr amplitude has no direction and so amplitude is always positive So Particles, depending on the type of wave can only move perpendicular or parallel, so its displacement of each particle is shown by an oscilliscope deviceĪmplitude The maximum displacement of a particle from its equilibrium state And also the the distance between two wavefronts is the wavelengthĭisplacement of a wave The distance of a particle in a wave from its equilibrium state in a specified direction It is used to represent the crests of the wave. Wavefronts It is an imaginary line which is drawn through the crest of the wave which is perpendicular to the direction of the wave Rarefractions are regions of the longitudinal wave where particles are far apart / low pressureĬompressions are regions of the longitudinal wave where particles are squashed together ![]() So this wave contains rarefractions and compressions Longitudinal waves Waves which particles vibrate parallel to the direction of the wave energy They contain points called crests and troughsĬrest and troughs are points in the transverse waves where particles have maximum displacement(amplitude).Įxamples are electromagnetic waves and water waves Transverse waves Waves which particles vibrate perpendicular to the direction of the wave energy You will need to know some basic terms which are related to this topic Back Next Waves, Intensity & Doppler's Effect
