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

0.5 m

Explanation

Solution

: Length of dipole antenna

=λ2=c2υ=3×1082×3×108=0.5m= \frac{\lambda}{2} = \frac{c}{2\upsilon} = \frac{3 \times 10^{8}}{2 \times 3 \times 10^{8}} = 0.5m
