Aradio transmitting station operating at a frequency of 120 mhz has two identical antennas that radiate in phase. antenna b is 9.00 m to the right of antenna a. consider point p between the antennas and along the line connecting them, a horizontal distance x to the right of antenna a. for what values of x will constructive interference occur at point p?

x = 4.5 m, 5.75 m, 6.5 m, 8.25 m

Explanation:

= frequency of radio transmitting station = 120 MHz = 120 x 10⁶ Hz

= speed of the radio wave = 3 x 10⁸ ms⁻¹

= wavelength

Wavelength is given as

= distance between the two antennas = 9.00 m

= Distance of point P from the antenna A

= Distance of point P from the antenna B

= Path difference

Path difference is given as

For constructive interference, Path difference is given as

For n = 0

For n = 1

For n = 2

For n = 3

260 miles per hour

explanation:

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
