Progressive Waves
Progressive waves are those waves having visible disturbances meaning the vibrations can be seen moving throughout the material.
Standing/Stationary Waves
Standing waves are produced when two waves interfere this results in an invisible disturbance though the wave is moving throughout the material. Standing waves consist of two different points known as nodes and antinodes.
Nodes: These are points in the wave that have zero energy and displacement.
Anti-Nodes: These are points in the wave that have the highest energy or amplitude.
The distance between two consecutive nodes or anti-nodes makes half a wavelength.
Waves formed from stringed and wind instruments are stationary waves. Open ends always have an antinode while closed ends have a node.

I'm still fascinated with the clear way in which you put through such difficult physics concepts. Congratulations! Many Physics teachers may envy you.
ReplyDeleteI think its very good article and its described in a very well manner.
