QJEEM23Ph39c6: JEE Main 2023 Physics - Class 12 JEEM23Ph39c6 Solution: The power radiated from a linear antenna of length is…

The power radiated from a linear antenna of length ll is proportional to

(Given, λ=\lambda= Wavelength of wave):

Multiple Choice Options

  • A (lλ)2\left(\frac{l}{\lambda}\right)^{2}
  • B lλ2\frac{l}{\lambda^{2}}
  • C l2λ\frac{l^{2}}{\lambda}
  • D lλ\frac{l}{\lambda}

Step-by-Step Verified Solution

The power radiated by a linear antenna is typically determined by its physical length relative to the wavelength of the signal it is transmitting or receiving. The power radiated from a linear antenna of length 'l' is proportional to the square of the ratio of its length to the wavelength, represented as (lλ)2(\frac{l}{\lambda})^{2} .
