Radio Stations Often Have More Than One Broadcasting Tower Because

question 142

Multiple Choice

Radio stations often have more than one broadcasting tower because federal guidelines do not usually permit a radio station to broadcast its signal in all directions with equal power. Since radio waves can travel over long distances, it is important to control their directional patterns so that radio stations do not interfere with one another. Suppose that a radio station has two broadcasting towers located along a north-south line, as shown in the figure. If the radio station is broadcasting at a wavelength and the distance between the two radio towers is equal to , then the intensity I of the signal in the direction is given by where I _o is the maximum intensity. Approximate I in terms of I _o for .

• A)I _o
• B)0.614I _o
• C)0.625I _o
• D)0.603I _o
• E)0.592I _o
