Each disturbance corresponds to a force, and all forces add ### Interference Interference – a special case of superposition Constructive interference – two identical waves arrive at the same point exactly in phase. - The result - Amplitude is increased. - The wavelength is the same. Destructive interference – two identical waves arrive at the same point exactly out of phase. - The result - Amplitude is zero ### Slide Deck <div style="position: relative; width: 100%; height: 0; padding-top: 56.2500%; padding-bottom: 0; box-shadow: 0 2px 8px 0 rgba(63,69,81,0.16); margin-top: 1.6em; margin-bottom: 0.9em; overflow: hidden; border-radius: 8px; will-change: transform;"> <iframe loading="lazy" style="position: absolute; width: 100%; height: 100%; top: 0; left: 0; border: none; padding: 0;margin: 0;" src="https://www.canva.com/design/DAGPwO6kTks/6R2_veKIGNky22X2zmEn4w/view?embed" allowfullscreen="allowfullscreen" allow="fullscreen"> </iframe> </div> ### Related Topics --- [[Home|Home]] | [[Oscillations]] | [[Waves]] | [[Module 0 Sound]] | [[Electromagnetic radiation]]
