It is known that the height of a transmission antenna should preferably be of the order. The length of antenna at a place is 0.75 m. Its optimum transmission frequency would be (nearly)
(1) 25 MHz
(2) 50 MHz
(3) 75 MHz
(4) 100 MHz
Correct option: (4) 100 MHz
Explanation:
Length of antenna required = λ/4
