The description of a periodic motion, in general, and oscillatory motion, in particular, requires some fundamental concepts, like period, frequency, displacement, amplitude and phase. These concepts are developed in the next section. 13.2 PERIODIC AND OSCILLATORY MOTIONS. Fig. 13.1 shows some periodic motions.

OSCILLATIONS AND WAVES. 4.1 Harmonic Oscillation. 4.1.1 Springs and the Simple Harmonic Motion (SHM) Periodic Motion. A periodic motion is a motion of an object that regularly returns to a given position after a fixed time interval. Simple Harmonic Motion (SHM) The force is proportional to the distance from the equilibrium position.
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.
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.
15.1 Simple Harmonic Motion. Periodic motion is a repeating oscillation. The time for one oscillation is the period T and the number of oscillations per unit time is the frequency f. These quantities are related by \(f = \frac{1}{T}\).
An object on the end of a spring is oscillating in simple harmonic motion. If the amplitude of oscillation is doubled, how does this affect the oscillation period T and the object’s maximum speed vmax? T and vmax both double.
