Lecture Physics A2: Interference - PhD. Pham Tan Thi present the content a single oscillating wave, multiple waves - superposition, superposing sinusoidal waves, adding sine waves with different phases, . | Interference Pham Tan Thi . Department of Biomedical Engineering Faculty of Applied Science Ho Chi Minh University of Technology A Single Oscillating Wave The formula y x t Acos kx t describes a harmonic plane wave of amplitude A moving in the x direction For a wave on a string each point on the wave oscillates in the x direction with simple harmonic motion of angular frequency ω 2 The wavelength The speed velocity v f k k The intensity is proportional to the square of the amplitude I A2 Multiple Waves Superposition The principle of superposition states that when two or more waves of the same type cross at a point the resultant displacement at that point is equal to the sum of the displacements due to each individual wave. For inequal intensities the maximum and minimum intensities are Imax A1 A2 2 Imin A1 - A2 2 Multiple Waves Superposition Constructive Superposition Destructive Superposition ou added the two sinusoidal waves shown Superposing Sinusoidal Waves at would the result look like If we added the two sinusoidal waves shown what would the result look like 1 .0 0 0 .5 0 0 .0 0 1000 100 200 300 400 500 600 700 800 900 0 - 0 .5 0 - 1 .0 0 of two sines having the same frequency is another same frequency. ude depends on their relative phases. 2 .0 0 1 .5 0 1 .0 0 0 .5 0 ou added the two sinusoidal waves shown 1 .0 0 0 .5 0 Superposing Sinusoidal Waves at would the result look like 0 .0 0 1000 100 200 300 400 500 600 700 800 900 0 - 0 .5 0 If we added the two sinusoidal waves shown what would the result - 1 .0 0 look like 1 .0 0 0 .5 0 0 .0 0 of two sines having the same frequency is another s 1000 100 200 300 400 500 600 700 800 900 0 - 0 .5 0 - 1 .0 0 same frequency. The sum of two sines having the same frequency is another sine ude depends with the sameon their relative frequency Its amplitudephases. depends on their relative phases of two sines having the same frequency is another 2 .0 0 1 .5 0 same frequency. 1 .0 0 0 .5 0 ude depends on their relative
