Question

Ex. 14 A certain fringe width is observed
when green light of wavelength 5350 A.U. is
used where the distance between the slit and
the screen is 1.28 m. What should be the
distance between the slit and screen if the red
light of wavelength 6400 AU is used to get the
same fringe width without disturbing the
distance between the coherent sources ?ubonq

Q3. Amicrowave transmitter is used to direct microwaves of wavelength 30 mm along a line XY. A metal plate is positioned at right angles to XY with its mid-point on the line, as shown. A B C X D transmitter When a detector is moved gradually along XY, its reading alternates between maxima and minima. Which one of the following statements is not correct? The distance between two minima could be 15 mm. The distance between two maxima could be 30 mm. The distance between a minimum and a maximum could be 30 mm. The distance between a minimum and a maximum could be 37.5 mm. detector metal plate Y
The figure below shows a radio wave transmitter and a receiver separated by a distance d = 50distance d = 50, 0 m, both being at a height h = 35, 0 m above the ground. The receiver canThe receiver can receive signals either directly or indirectly from reflected signals on the ground. Suppose that theground is leveled and a 180o phase shift occurs in the reflection.Determine the longest wavelengths that interferea. constructively;b. destructively.
In a single-slit diffraction pattern, the central fringe is 480 times as wide as the slit. The screen is 16,000 times farther from the slit than the slit is wide. What is the ratio X/W, where is the wavelength of the light shining through the slit and W is the width of the slit? Assume that the angle that locates a dark fringe on the screen is small, so that sin is approximately equal to tan (). Number Units
