According to theoretical study of radiation from a same linear antenna, the power radiated is proportional to [ = wavelength ]

Options

  1. A⁻²
  2. B⁻¹
  3. C²

Correct answer

A. ⁻²

Step-by-step solution

A linear antenna radiates power proportional to ( 1 )² . Hence a longer antenna emits more power. Also power radiated by a long wavelength base would be small.
