δ=λ2-λ1=δ2(1-sinα)
If the first minimun(δ=λ/2)
occur when θ= 24°then
α =180-(θ+90+θ)=42°
δ2 = 1/(1-sinα)
= [(266/2)]/1-sin42°=133/0.330
=403 m
h=δ2sin24°= 163 m

Radio waves from a star, of wavelength 228 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 off the water. The first minimum of destructive interference occurs when the star is theta = 26.0 degree above the horizon. Find the height of the cliff. (Assume...

Radio waves of wavelength 174 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 θ = 24.5° above the horizon....

12. The waves from a radio station can reach a home receiver by two paths. One is a straight- line path from transmitter to home, a distance of 30.0 km. The second is by reflection from the ionosphere (a layer of ionized air molecules high in the atmosphere). Assume this reflection takes place at a point midway between receiver and transmitter, the wavelength broadcast by the radio station is 350 m, and no phase change occurs on reflection. Find the...

9.) Two antennas, 6 meters (m) apart, transmit coherent, monochromatic radio waves, to two receivers, A and B. Receiver A is the same distance from both antennas (about 8.5 m). Receiver B is 8m from one antenna, and 10m from the other I both antennas transmit 3m waves with wavelength of 1.0 meters, then what type of interference will be experienced by the receivers? 8 A) receiver A: constructive; receiver B: constructive B.) receiver A: constructive; receiver...

A 500-m-diameter radio telescope detects radio waves with a 5.00 cm average wavelength. How close together could these point sources be at a nearby galaxy (the Large Megallanic Clouds) if the distance to the galaxy is 163,000 light years?

2.1.1. Two coherent sources, A and B, of radio waves are 40.0 cm apart. Each source emits waves with wavelength 50.0 cm. Consider points along the line between the two sources. At what distances from A, if any, is the interference (a) constructive, (b) destructive? 2.1.2. A coherent source of monochromatic light of unknown wave- length shines on double slits separated by 0.40 mm. Bright spots separated by 0.80 cm appear on a screen 5.0 m away. What is the...

An astronomical radio telescope consists of two antennas
separated by a distance of 206 m. Both antennas are tuned to the
frequency of 24 MHz. The signals from each antenna are fed into a
common amplifier, but one signal first passes through a phase
selector that delays its phase by a chosen amount so that the
telescope can "look" in different directions. When the phase delay
is zero, plane radio waves that are incident vertically on the
antennas produce signals...
