Radio Waves From A Star Of Wavelength 350 M Reach A Radio Telescope By Two Separate Paths As Shown In The Figure Belo 1 (14.92 KiB) Viewed 47 times

Radio waves from a star, of wavelength 350 m, reach a radio telescope by two separate paths, as shown in the figure below (not drawn to scale). One is a direct path to the receiver, which is situated on the edge of a cliff by the ocean. The second is by reflection of the water. The first minimum of destructive interference occurs when the star is 0 - 26.0 above the horizon. Find the height of the clift. (Assume no phase change on reflection. The image is not drawn to scale, assume that the height of the radio telescope is negligible compare to the height of the cliff) Direct path Radio telescope Reflected path
