Homework Statement
A Hertzian dipole is short compared with the wavelength of the radiation it emits. It describes ’short’ radio antennas and the scattering of electromagnetic radiation by small particles.
(a) Give an upper limit for the length of a Hertzian dipole antenna operating at 300 kHz and for the size of atmospheric particles that can be considered as Hertzian dipole scatterers at 1014 Hz.
Homework Equations
Well it says the dipole is short in comparision the the wavelength it emits... So: L << c/f ? But I'm not sure...
The Attempt at a Solution
At 300Hz - L(upper limit) = 3*10^8/300*10^3 m (this seems obscenely big...)
Where am I going wrong? Thanks
