Sound waves are both Longitudinal and Transverse , and different from Light waves which are Transverse waves. Learn about sound velocity, amplitude, frequency , pitch . Animations are included to show the sound wave moving .
Following topics are covered:
1) Get a feel for sound waves
2) String Vibrations :
a) Longitudinal vibrations
b) Transverse vibrations
3) Speed of Sound in Solids
4) Speed of Sound in a Gas : Newton’s equation and Laplace’s Correction
5) Sound: its main defining aspects :
- Pitch and Frequency
- Intensity and Loudness
- Quality
6) Standing Waves and Air Columns : equations
a) Pipe closed at one end
b) Pipe open at both ends
7) Beats
8) Doppler Effect and example /cases:-
a) Train moving, person is stationary
b) Train stationary, person moving towards the train
