Question

What is frequency of a sound wave?

• A. Number of oscillations per unit time.
• B. Time gap between two oscillations.
• C. Distance between two oscillations.
• D. Time gap between two peaks.

Answer 1

The correct option is A

Number of oscillations per unit time.

The number of vibrations made by a particle of the medium in one second is called the frequency of a sound wave. It is same as the number of waves passing through a point in one second.
