Question
Back in ancient times, before the advent of cable and satellite TV, television signals used to be broadcast through the air, and received by an antenna sitting on top of your TV set. This antenna usually consisted of a pair of metal wires arranged 111 the shape of a "V", and was called "rabbit ears". You may not know it, but those broadcasts are still in operation, to bring television signals to those few poor souls who don't have cable, satellite, HDTV, or better ways to spend their time. In North America, channel 2 is carried by a wave with a frequency of 55.25 MHz. Suppose I have rabbit ear antennas, that are one meter long. If I'm watching channel 2, what is the difference in phase from one end of the antenna to the other?Explanation / Answer
we have
v= f, v--> velocity of the wave in this case c, speed of light
f--> frequency and --> wavelength
c= f
3*10^(8)=55.25*10^(6)*
=5.43m
/(2)= l/(), l= 1m in this case as given
= 1.157 radians or =66.26 degree
