CBSE Class 11 Physics Notes Chapter 14: We shall discover a great deal more in this piece. A basic pendulum, which consists of a particle suspended by a thread in the earth's gravitational field, oscillates as an example of a little oscillation. The chapter also explains damped oscillations. Undamped oscillations may result from a periodic modification in the oscillating system's characteristics in addition to a periodic external push. We call this parametric resonance.

CBSE Class 11 Physics Notes Chapter 14
A motion that repeats itself repeatedly at regular periods of time is referred to as periodic motion. An item moving repetitively to and fro or back and forth at a fixed point over a predetermined period of time is referred to as being in oscillatory or vibratory motion.

TIME PERIOD OF S.H.M
Use these procedures to determine if a motion is S.H.M. and to calculate its duration: By balancing every force acting on the equilibrium position, find its location analytically. Move the particle in the likely direction of oscillation by a displacement 'x' from the mean position. Find its net force and see if it is moving in the direction of the mean. Attempt to represent net force as a function of its displacement, "x," in proportion. It is a simple harmonic motion if steps (c) and (d) are proven.Oscillations of a Block Connected to a Spring
Horizontal spring:
Suppose a block of mass m be placed on a smooth horizontal surface and rigidly connected to a spring of force constant K whose other end is permanently fixed.
Vertical Spring:
When the spring is suspended vertically from a fixed point and carries the block at its other end as shown, the block will oscillate along the vertical line.
Combination of springs:

Springs in series:
Oscillation of a Cylinder Floating in a Liquid:
Suppose a cylinder of mass m and density d be floating on the surface of a liquid of density ρ 𝜌. The total length of the cylinder is taken to be L.
DOPPLER EFFECT
According to Doppler's effect, the apparent frequency of sound perceived by the listener and the actual frequency of sound emitted by the source differ whenever there is a relative motion between the source and the listener.Sign Convention
Every velocity in the direction from S to L is considered positive, and every velocity in the direction from L to S is considered negative. The components of the source and listener's velocities along the line connecting them would be taken into account if the motion was in a different direction.Benefits of CBSE Class 11 Physics Notes Chapter 14
