Correct Answer
(D) 25 m
Step-by-step Solution
Detailed explanation
\(\mathrm{f}_{\mathrm{c}}=3 \mathrm{MH}_{\mathrm{z}}=3 \times 10^6 \mathrm{H}_{\mathrm{z}}\) \(\therefore\) Wavelength, \(\lambda=\frac{\mathrm{c}}{\mathrm{f}}=\frac{3 \times 10^8}{3 \times 10^6}=100 \mathrm{~m}\) \(\therefore\) Size of the antenna,…
