Two radius antennas radiating wave in phase are located at point `A` and `B` ,`200m` part(figure) The radio waves have a frequency of `6MHz`.A radio receiver in moved out form point`B` along a line perpendicular to the line connecting `A` and `B`(line`BC` shown in figure)at time distances from `B` will there be destructive interference?

Two radio transmitters radiating in phase are located at point A and B, 250 m apart. The ratio wave have frequency of 3MHz. A radio receiver is moved out from point B along a line BC (perpendicular to AB). The distance from B beyond which the detector does not detect any minima si :

Two identical loudspeakers are located at points A & B, 2 m apart. The loudspecakers are driven by the same amplifier. A small detector is moved out from B along a line perpendicular to the line connecting A & B. Taking speed of sound in air as 332 m"/"s . Find the frequency below which there will be no position along the line BC at which destructive interference occurs.

Two identical loudspeakers are located at point A & B, 2 m apart. The loudspeakers are driven by the same amplifier (coherent and are in phase). A small detector is moved out from point B along a line frequency below which there will be no position

The perpendicular distance of the point c from the line joining a and b is

Consider two points A and B and a line L as shown in figure. Find bar(AB)

The displacement of a vibrating string versus position along the string is shown in the figure. The periodic wave have a speed of 10.0cm/s. A and B are two points on the string. What is the difference in phase between the points A and B?
