Q.) Define Frequency and Time Period, and explain the relationship between them. (50 words /5 marks)

Read in:
  • Frequency : The total number of complete oscillations (or waves) produced in one second in a medium is called frequency.
  • Unit : Hertz (Hz) or per second (s⁻¹)
  • Dimension : [M⁰ L⁰ T⁻¹]
  • Time Period : The time taken to complete one full oscillation (or one complete wave) is called the time period.
  • Unit : Second (s)
  • Dimension : [M⁰ L⁰ T¹]
  • Relationship : Frequency (ν) and Time Period (T) are inversely proportional to each other.
  • Formula : ν = 1/T
