Resonance, resistance in electrical circuits. The most important quantity to calculate is the power absorbed from the driving force by the oscillator. As a function of frequency, the power absorbed is a very characteristic ., or ., with a maximum at the frequency of the undamped oscillator. We shall finally l

Equations for Waves,t we did not know the constant of proportionality, which clearly depends on the properties of the medium through which the wave is travelling. Similarly, we need an equation of motion to deal with . of various kinds. For example, in the microwave tunnelling experiment described in section 2.7, altho

The Simple Harmonic Oscillator and Superposition of Vibrations, the important case of light travelling through a vacuum, however, we must interpret ‘displacement’ differently. It will be recalled that light is not propagated by means of vibrations of a jelly-like aether; we must simply regard the displacement as an oscillating electric field, with which is associated an oscillating magnetic field.

Waves and Particles,ve type of detector known as a photomultiplier tube (described in Wehr and Richards, ., 2nd edn, Addison-Wesley, section 10.5), a beam of low-intensity X-rays is detected as a sequence of isolated sharp pulses, such as would be produced by a stream of particles arriving at the detector.
