About this Episode
We continue to look at mechanical waves, focusing on sound and hearing, specifically the decibel units for sound level.
Recent Episodes from Physics 50 Lectures @ SJSU
Review of chapters 13-16
We review oscillation and simple harmonic motion, fluid mechanics, waves and sound.
Doppler Shift and Interference
We look at wave effects for sound including interference and beat notes and the doppler shift caused by a moving listener or source.
Sound and Hearing
We continue to look at mechanical waves, focusing on sound and hearing, specifically the decibel units for sound level.
Mechanical Waves
We introduce waves by considering solutions to the wave equations for propagation along a string. We introduce the concepts of superposition and standing waves.
Fluid Dynamics
We introduce the continuity equation for mass and volume flow rate and the Bernoulli equation for relating pressure, height and speed of fluid.
Hydrostatics
We introduce density, pressure and the buoyant force and derive Pascal's law for fluids.
Periodic Motion
We look at parameters of periodic motion. Specifically we investigate simple harmonic motion and the pendulum.
Review of chapters 9-12
Review of angular motion and equilibrium
Gravitation
We look at Newton's law of gravitation and introduce the universal gravitational constant. We also discuss escape velocity and black holes.
