Class 11 Physics Chapter 14: Chapter Summary & Sub-topics

Oscillatory motion deals with an object’s to and fro motion from its initial position. In the absence of friction, an item can remain in oscillatory motion indefinitely, however, this is not possible due to equilibrium.

In addition, Galileo found four major moons of Jupiter in 1610.  Each moon appeared to move back and forth relative to the planet in a simple harmonic motion to him, with the planet’s disc serving as the motion’s halfway. The handwritten record of his observations is still available.

Galileo used his pulse beats to estimate the periods of a swinging chandelier in a cathedral.  He saw that the chandelier’s movement was regular. The system is similar to  a pendulum. Free oscillations can be seen in a person swinging without being pushed or in a  simple pendulum that has been pushed and released. In both cases,   the swing amplitude will gradually decrease, and the system will eventually come to a standstill. The free oscillations cannot be sustained in practice due to the ever-present dissipative forces. 

The phenomenon of amplitude increasing when the driving power is close to the oscillator’s natural frequency is known as resonance. We encounter resonance-related events in our daily lives.

Your swinging experience is a good example of resonance. You may have realised that the key to swinging to greater heights is to synchronise the rhythm of pushing against the ground with the natural frequency of the swing. The real oscillator and its motion are then described as damped.

A combination of two simple harmonic motions with arbitrary amplitudes and phases is not always periodic. It’s only periodic if one motion’s frequency is an integral multiple of the other’s frequency. A periodic motion, on the other hand, may always be described as the sum of an unlimited number of harmonic motions of varying amplitudes.

Any periodic motion of an object at a distance around the equilibrium position that repeats itself over a length of time is characterized as oscillation. Oscillation up and down of a spring, oscillation swinging side by side of a pendulum also known as Simple harmonic motion and so on are examples of oscillation.

The oscillation where the body oscillates under the influence of an external periodic force is known as forced oscillation. When learning about forced oscillations, it’s vital to remember the phrase resonance. The frequency of the external force must be equal to the oscillator’s natural frequency to be considered resonant. The resonant frequency is another name for this frequency.

To do so,  students must read the chapter thoroughly and highlight all  key points that they consider vital.  Besides this, the different formulas and laws endorsed in this chapter are  crucial for the learner to be familiar with and practice all questions to test their understanding and for self-assessment. They should also refer to the NCERT solutions to help them  brush up  their concepts. These basic measures will assist the learner in performing well on the exam.

According to the Doppler effect, when there is a relative motion between the source of sound and the listener, the frequency of the sound heard by the listener is completely different from the frequency of the sound emitted by the source.
