Q75 / 90 · JEE Main 2019 (09 Apr Shift 2) · Physics

The physical sizes of the transmitter and receiver antenna in a communication system are:

A
proportional to carrier frequency
B
independent of both carrier and modulation frequency
C
inversely proportional to modulation frequency
Correct answer
D
inversely proportional to carrier frequency

Solution

The physical sizes of transmitter and receiver antenna are directly proportional to carrier wave wavelength or inversely proportional to carrier wave frequency.

Hence, the correct answer is option: 'D'.
