Radio waves of wavelength 102 m from a galaxy reach a radio telescope by two separate paths as shown in the figure below. One is a direct path to the receiver, which is situated on the edge of a tall cliff by the ocean, and the second is by reflection off the water. As the
galaxy rises in the east over the water, the first minimum of destructive interference occurs when the galaxy is e = 28.5° above the horizon. Find the height of the radio telescope dish above the water.

- Radio waves from a star, of wavelength 2.50 3 102 m, reach a radio telescope by two separate paths, as shown in Figure P24.13. 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 off the water. The first minimum of destructive interference occurs when the star is u 5 25.0° above the horizon. Find the height of the cliff. (Assume no phase change on reflection.)arrow_forwardDiffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 9.00 cm passes through a slit 12.0 cm wide. A microphone is placed 8.00 m directly in front of the center of the slit, corresponding to point O in Fig. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O. At what distances from O will the intensity detected by the microphone be zero?arrow_forwardYou are operating a new radio telescope that has been installed on a tall cliff facing the ocean. You begin the testing of the telescope by facing the antenna toward the ocean, setting its receiving wavelength to 125 m, and sweeping its direction slowly from horizontal to straight up in the sky.Each sweep takes about an hour. When you review the data, you notice that the antenna received no signals when aimed at a certain angle above the horizontal. You continue to take data beginning at the same time each night and discover that the angle at which no signals are detected varies from night to night. Over a full month, the angle at which no signals are detected varies from 24.5° to 25.7°. You finally figure out that the loss of signal is due to destructive interference caused by the reflection of radio waves from the ocean surface, and the monthly variation is due to the changes caused by ocean tides. You inform the local oceanographic institute that you have a novel method of measuring…arrow_forward

Each bubble has the shape of a spherical shell and a refractive index of 1.35. Bubble A has a wall thickness of 100 nm.

Assume the ground is level between the transmitter and receiver and a 180° phase shift occurs upon reflection.

- Radio waves from a transmitter can be received after traversing a direct path a or an indirect path b involving a ground reflection. This often leads to destructive interference and fading signals in urban area. As shown in the diagram, a transmitter at 88.5 MHz and receiver are located on the rooftop of two separate buildings each 60 meters high, with bare ground between them. What is the maximum separation of buildings that will lead to destructive interference at the receiver? Ignore the reflection phase shift of path b. (1 MHz = 106 Hz)arrow_forwardA thin layer of oil with index of refraction no = 1.47 is floating above the water. The index of refraction of water is nw = 1.3. The index of refraction of air is na = 1. A light with wavelength λ = 325 nm goes in from the air to oil and water. Part (a) Express the wavelength of the light in the oil, λo, in terms of λ and no. Part (b) Express the minimum thickness of the film that will result in destructive interference, tmin, in terms of λo. Part (c) Express tmin in terms of λ and no. Part (d) Solve for the numerical value of tmin in nm.arrow_forwardTwo sources are emitting coherent, monochromatic EM waves with a wavelength of 2 cm in air. Source 1 is embedded in a material with index of refraction n1 = 1.5. The distance between source 1 and the edge of the material is 6 cm. You can assume nair = 1. At the point marked with an X, which is 9 cm from source 2 and 3 cm from the edge of the material that source 1 is embedded inside, what kind of interference will you find between EM waves from the two sources?
