PHYS-P 105 1st Edition Lecture 1Outline of Last Lecture I. Not ApplicableOutline of Current Lecture II. What is Sound?III. Waves IV. Classical Mechanics Current Lecture- Science of Sound = Acousticso Every wave has a fundamental frequency o Frequency = Cycles per second o Wave length = Distance for one complete cycle o Speed of wave = velocity = frequency(wavelength)- Wave = Transverse/Longitudinal o All waves transport information o Transmission of energy in wave = carried out by cycles of physical objects o Most familiar sound source = created by vibrating bodies o Travel in solids, liquids and gaso Sound wave = longitudinal Molecules travel forward and backward Acoustic energy = Transported forwards o Periodic Motion = Motion that repeats in equal time intervals o Psychoacoustic = When brain understands sound perception - Classical Mechanics o Sound wave is produced by mechanical vibration of objects o Longitudinal pressure disturbance of a medium o Mechanics = Study of motion of physical objects o Classical Relativistic = Motion of particle is much slower than speed of light Quantum Mechanics = Size of moving body is much larger than size of atomsThese notes represent a detailed interpretation of the professor’s lecture.
