The length of a dipole antenna for a carrier wave of frequency 6 ×...

Length of the& antenna

$= \dfrac{λ}{2} = \dfrac{c}{2υ}$

( Where $c$ = speed of light =& $3 \times {10}^{8}ms^{- 1}$, $υ$ = frequency =& $6 \times {10}^{8}Hz$ )

putting these values in formula above&

Length =& $\dfrac{3 \times {10}^{8}}{2 \times 6 \times {10}^{8}} = 0 . 25m$&
