In vacuum, all electromagnetic waves have the same speed c, whose value is : c = 299, 792, 458 ms–1. (14.1) A third kind of wave is the so-called Matter waves. They are associated with constituents of matter : electrons, protons, neutrons, atoms and molecules.
The most familiar type of waves such as waves on a string, water waves, sound waves, seismic waves, etc. is the so-called mechanical waves. These waves require a medium for propagation, they cannot propagate through vacuum. They involve oscillations of constituent particles and depend on the elastic properties of the medium.
Waves Summary Notes. Waves transfer energy The higher the amplitude the greater the energy of the wave. f=no. of waves produced per second T= time for 1 wave to pass a point. Transverse Wave: The particles of the medium transmitting the wave travel at right angles to the direction of energy travel. e.g. E.M. waves.

Waves Notes PDF. The Class 11 Physics notes is a written explanation for every passage or concepts included in the chapter Waves. These Waves notes are available in the Portable Document Format. The PDF of the Class 11 Physics Notes can be easily downloaded without any difficulty.
A progressive wave transfers energy without transferring material and is made up of particles of a medium (or field) oscillating e.g. water waves are made of water particles moving up and down.
