What should be the length of the diploe antenna for a carrier wave of frequency `3 xx 10^(8) Hz`?

Explanation

Here, `v = 3 xx 10^(8)Hz`,
`c= 3xx10^(8)m//s`
Length of dipole antenna `= lambda/2 = c/2v`
(Hertz Antenna)
` = (3 xx 10^(8))/(2 xx 3 xx 10^(8)) = 0.5m`
This antenna is not grounded.
On the other hand, Marconi antenna is grounded and its length ` = lambda/4 = c/4 v = (3xx10^(8))/(4xx3xx10^(8))`
`= 0.25 m`
