Question

Field strength of tropospheric TV signal is proportional to

• A. $\frac{1}{\lambda }$
• B. $\lambda$
• C. $\frac{1}{{\lambda }^2}$
• D. ${\lambda }^2$

Answer 1

The correct option is A $\frac{1}{\lambda }$

Electnc field strength, $E=\frac{88\sqrt{p}{h}_t{h}_r}{\lambda d^2}$
$⟹E\propto \frac{1}{\lambda }$
