Intro to Waves, Pulses, EM and Sound, Energy, Vibrations, Oscillations - Physics

This video explains waves and wave pulses, including sound and electromagnetic waves, properties (wavelength, frequency, period, amplitude), the derivation of wave speed in a string, speed of sound in different mediums (solids, liquids and gases), compression and rarefaction, transverse vs longitudinal waves, wave amplitude and energy carried by a wave.
