Problem 38P
A television is tuned to a station broadcasting at a frequency of 6.60 × 107 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:
Step 1 of 2
The length of the antenna equal to half a wavelength of the broadcast signal, so we can write the equation for the length of the antenna as,
Wavelength is given by,
Substitute this value in equation one.
