Question 1
If a certain transmission medium allows a phase velocity of 2x10^8 m/s and has a group velocity of 1.5x10^8 m/s, calculate the ratio of phase velocity to group velocity.
💡 Hint: Divide phase velocity by group velocity to find the ratio.
Question 2
Discuss how the understanding of both velocities can aid in the design of effective RF communication systems.
💡 Hint: Consider the roles of data integrity and signal delay.
