Consider the following statement In damped oscillation, the amplitude of oscillation decreases exponentially due to damping forces. In damped oscillation, the frequency of the oscillation is slightly reduced.   Which of the following statement is correct? Correct Answer Both 1 and 2

CONCEPT:

  • Damped oscillation: The oscillation of a body whose amplitude goes on decreasing with time are defined as a damped oscillation.

EXPLANATION:

  • In actual practice, most of the oscillations occur in viscous media, such as air, water, etc.
  • A part of the energy of the oscillating system is lost in the form of heat, in overcoming the resistive force.
  • As a result, the amplitude of such oscillations decreases exponentially with time. Therefore statement 1 is correct.
  • In damped oscillation, the frequency of the oscillation is slightly reduced. Therefore statement 2 is correct.
