Question

A television is tuned to a station broadcasting at a frequency of 2.04 * 108 Hz. For best reception, the rabbit-ear antenna used by the TV should be adjusted to have a tip-to-tip length equal to half a wavelength of the broadcast signal. Find the optimum length of the antenna.

Answer 1

Answer:

L= 0.75m

Explanation:

To develop the exercise we need to use the Frequency equation, so,

$f=\frac{c}{\lambda}$

$f= \frac{c}{2L}$

$L= \frac{c}{2f}$

$L = \frac{3*10^8m/s}{2*(2.04*10^8Hz)}$

$L= 0.75m$
