Practicing Success
What is observation that we make when we transmit the following frequencies over an antenna ? |
Length of the antenna increases with increase in frequency of transmission. Length of the antenna decreases with increase in frequency of transmission. Length of the antenna is the same for all frequencies. Length of antenna depends upon the distance of transmission. |
Length of the antenna decreases with increase in frequency of transmission. |
\(\lambda\) = \(\frac{c}{\nu}\) c = 3 x 108 m/s ; \(\nu\) = 3000 MHz length of antenna : = \(\frac{\lambda}{4}\) = 0.05 m
\(\lambda\) = \(\frac{c}{\nu}\) c = 3 x 108 m/s ; \(\nu\) = 300 MHz length of antenna : = \(\frac{\lambda}{4}\) = 0.5 m
\(\lambda\) = \(\frac{c}{\nu}\) c = 3 x 108 m/s ; \(\nu\) = 30 MHz length of antenna : = \(\frac{\lambda}{4}\) = 5 m
Length of the antenna decreases with increase in frequency of transmission. |
