Question

What should be the length of the dipole antenna for a carrier wave of frequency 3 x 108 Hz?

• A. 1 m
• B. 0.5 m
• C. 2 m
• D. 2.5 m

Answer 1

Answer: (B)

0.5 m

Answer 2

: Length of dipole antenna

$= \frac{\lambda}{2} = \frac{c}{2\upsilon} = \frac{3 \times 10^{8}}{2 \times 3 \times 10^{8}} = 0.5m$
