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.
The electromagnetic waves that you will learn in Class XII are a different type of wave. Electromagnetic waves do not necessarily require a medium - they can travel through vacuum. Light, radiowaves, X-rays, are all electromagnetic waves. In vacuum, all electromagnetic waves have the same speed c, whose value is : c = 299, 792, 458 ms –1. (15.1)
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.
chapter. Any material medium can be pictured as a collection of a large number of coupled oscillators. The collective oscillations of the constituents of a medium manifest themselves as waves. Examples of waves include water waves, seismic waves, electromagnetic waves. We shall study the wave phenomenon in the next chapter . 13.2.1 Period and ...
Summary. 16.1 Traveling Waves. A wave is a disturbance that moves from the point of origin with a wave velocity v. A wave has a wavelength λ λ, which is the distance between adjacent identical parts of the wave. Wave velocity and wavelength are related to the wave’s frequency and period by v = λ T λ T = λ λ f.
