Course content
Oscillations. Dynamics of an oscillating system. Free undamped oscillations, free damped oscillations, forced harmonic oscillations, resonance, pendulums, energy of oscillations, mean values of periodic quantities. Superposition and decomposition of oscillations. Superposition of oscillations having the same frequency, graphical method, goniometric method, vector representation of oscillations, method of the vector diagram, symbolic-complex method. Superposition of oscillations having different frequencies, superposition of oscillations having slightly different frequencies. Superposition of oscillations in different directions. Decomposition of complex periodic oscillations into harmonic components. Waves. Basic terms. Transverse and longitudinal waves, phase velocity of waves, wavelength, steady and transient waves, periodic waves, irregular steady waves. Wave equation, harmonic waves. Superposition of waves. Waves with the same frequency, waves of different frequencies, waves with slightly different frequencies. Standing waves and vibrations. Total standing waves, partial standing waves, vibration of points in a line, strings, bars, pipes. Waves in space. Huygense principle, wave reflection and refraction, interference of waves, wave diffraction, acoustic velocity and acoustic pressure, energy transferred by waves. Doppler principle. Velocity of waves in liquids, gases and solids. Acoustics. Sound, infrasound, ultrasound, threshold of hearing and threshold of pain, sound intensity levels, acoustic pressure levels. Superposition of irregular sounds, energetic principle of superposition.
