Energy and Momentum of Wavesaching the Earth from the Sun (power per square of surface of ~ 1 kW/m). Like moving particles, waves have momentum. However the existence of wave momentum should not cause doubt, although it is less noticeable than wave energy. For example, the light pressure of the Sun’s radiation on the Earth orbit is very small, p = 4.5 · 10. Pa .

Adiabatic Invariants. Propagation of Waves in Inhomogeneous Mediange in the parameter (of which an example is the oscillation of a pendulum whose length is changing slowly) is very interesting for a discussion of oscillations and waves, and at the same time it is often encountered in practice.

Linear Oscillatorsrent branches of science.” The philosophy and content of this chapter concerns this analogy, and we consider the properties of a linear oscillator, this being the basic model in the linear theory of oscillations and waves.
