Assertion : The surface wave propagation is used for medium wave band and for television broadcasting. Reason : The surface waves travel directly from transmitting antenna to receiver antenna through atomsphere.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Both assetion and reason are true and reason is the correct explanation of assertion. (For more detail, refer theory).

A transmitting antenna at the top of a tower has a height \(32 \mathrm{~m}\) and the height of the receiving antenna is \(50 \mathrm{~m}\). What is the maximum distance between them for satisfactory communication in line of sight (LOS) mode?

Assertion : The electromagnetic waves of shorter wavelength can travel longer distance on earth's surface than those of longer wavelengths. Reason : Shorter the wavelength, the larger is the velocity of wave propagation.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The electromagnetic waves of shorter wavelength do not suffer much difdfraction from the obstacles of earth's atmosphere so they can travel long distance.

A signal is to be transmitted through a wave of wavelength \(\lambda\), using a linear antenna. The length ' \(l\) ' of the antenna and effective power radiated \(P_{e f f}\) will be given respectively as- (K is a constant of proportionality)
1 \(\dfrac{\lambda}{8}, P_{e f f}=K\left(\dfrac{l}{\lambda}\right)\)
2 \(\dfrac{\lambda}{16}, P_{e f f}=K\left(\dfrac{l}{\lambda}\right)^{3}\)
3 \(\dfrac{\lambda}{5}, P_{e f f}=K\left(\dfrac{1}{\lambda}\right)^{\frac{1}{2}}\)
Length of antenna \(=\) comparable to \(\lambda\) Power \(P=\mu\left(\dfrac{1}{\lambda}\right)^{2}\) here \(\mu=k\) i.e., \(P = k{\left( {\frac{1}{\lambda }} \right)^2}\)
