Assertion (A): The group velocity is usually more than the phase velocity.
Reason (R): If the transmission line or transmission medium is such that different frequencies travel with different velocities, then the line or the medium is said to be dispersive.
  • a)
    Both A and R are true and R is a correct explanation of A.
  • b)
    Both A and R are true but R is not a correct explanation of A.
  • c)
    A is true but R is false.
  • d)
    A is false but R is true.
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Assertion (A): The group velocity is usually more than the phase veloc...
Group velocity is given by

Phase velocity or velocity of propagation is given by

The group velocity is usually less than the phase velocity. Hence, assertion is a false statement.
