Beat In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized. Tuning two … See more In physics, interference is a phenomenon in which two coherent waves are combined by adding their intensities or displacements with due consideration for their phase difference. The resultant wave may have greater … See more Because the frequency of light waves (~10 Hz) is too high for currently available detectors to detect the variation of the electric field of the light, it is possible to observe only the intensity of an optical interference pattern. The intensity of the light at a given point … See more • Active noise control • Beat (acoustics) • Coherence (physics) • Diffraction • Haidinger fringes See more The word interference is derived from the Latin words inter which means "between" and fere which means "hit or strike", and was coined by See more The principle of superposition of waves states that when two or more propagating waves of the same type are incident on the same point, the resultant amplitude at that point is equal to the See more Quantum interference is quite different from the classical wave interference described above.
