A beam of monochromatic light is incident on a single slit of width 0.610 mm. A diffraction pattern forms on a wall 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.08 mm. Calculate the wavelength of the light. ______nm One radio transmitter A operating at 55.5 MHz is 10.8 m from another similar transmitter B that is 180° out of phase with
A. How far must an observer move from A toward Balong the line connecting A and B to reach the nearest point where the two beams are in phase? ______ m
