Question

The number of virbration/oscillation executed per second is known as:
(a) Frequency
(b) Amplitude
(c) Wave length
(d) Pitch

Answer 1

Answer:

The number of virbration/oscillation executed per second is known as Frequency

Answer 2

The right answer to the asked question is Option A.

The number of vibration/oscillation executed per second is known as Frequency.

Oscillation is characterised as periodic motion. A motion is periodic if it repeats itself after a regular set of time intervals.

If an object moves back and forth on the same path, its movement is called as an oscillatory or vibratory motion. The frequency of such a motion is one of its most important physical characteristic.
