The number of oscillations or vibrations per second is referred to as the frequency of oscillation. It determines how often the particles of the medium vibrate when a sound wave passes through.

Understanding Frequency
Frequency is a fundamental concept in oscillations and waves, representing the number of cycles that occur in a given time period, specifically per second. It is denoted by the symbol 'f' and is measured in hertz (Hz).
Key Characteristics of Frequency:
- Definition: Frequency is defined as the number of complete oscillations or vibrations a system undergoes in one second.
- Formula: The basic formula to calculate frequency is:
- f = 1/T
- Where 'T' is the period (the time taken for one complete cycle).
Importance in Physics:
- Relation to Other Properties: Frequency is directly related to wavelength and speed of a wave through the equation:
- v = f × λ
- Where 'v' is the wave speed, 'f' is the frequency, and 'λ' (lambda) is the wavelength.
- Applications: Frequency is crucial in various fields including music, telecommunications, and physics, affecting how we perceive sound and light.
Conclusion:
In summary, frequency is a vital parameter that quantifies how often oscillations occur in a second, making it essential for understanding wave behaviors and their interactions across different mediums. Thus, the correct answer to the question is option 'C: frequency'.
