the length of an antennae operating at a frequency of 0.5 ghz is


570m

57.0m

5.70m

600 m
 

First you'll chose an antenna type, e.g. λ/2 dipole. If you know wavelength λ (spell: lambda), you'll know the antenna length.

but here nothing as such is given....:-(
 

600mm would be one wavelength, are you sure you are not missing an 'm' in the units of the last answer?
Even so, it is more usual for an antenna to be half or quarter wave so the answer would be 300mm or 150mm, both far less than the lowest figures you quoted.

no then i think that the question is wrong ...thank u..
 

λ = V/f

Velectron ~ 3*10^8

f = 0.5*10^6

λ = 600 m
