Question

The frequency of a sound wave is ____ to its time period.

  1. Perpendicular
  2. Equal
  3. Reciprocal
  4. Corresponds 

Hint:

The frequency of a sound wave is reciprocal to its time period.

The correct answer is: Reciprocal


    • The reciprocal of frequency is its time period.
    • f=1/T
    • Where, f= frequency and T= time period.
    • Frequency is no. of cycles per second.
