Question

The to and fro motion of a particle is called
(a) Oscillation
(c) Amplitude
(b) Pitch
(d) Frequency​

Answer 1

Explanation:

oscillation

Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current. ...

Answer 2

$\huge\mathfrak\blue{Question}$

The to and fro motion of a particle is called -

(a) Oscillation

(c) Amplitude

(b) Pitch

(d) Frequency

$\huge\mathbf\green{Answer}$

A - Oscillation .

required answer -

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium)

• Two or more different states. The term vibration is precisely used to describe mechanical oscillation.

• Familiar examples of oscillation include a swinging pendulum and alternating current.

for example -

• the beating of the human heart (for circulation),

• business cycles in economics, predator–prey population cycles in ecology,

• geothermal geysers in geology,

• vibration of strings in guitar and other string instruments .
