Light passes through a single slit. If the width of the sit is reduced, what happens to the width of the central bright fringe? O The central bright fringe becomes wider, because the angle that locates the first dark fringe on either side of the central bright fringe becomes smaller. O The central bright fringe becomes wider, because the angle that locates the first dark fringe on either side of the central bright fringe becomes larger. O The width of the central bright fringe does not change, because it depends only on the wavelength of the light and not on the width of the slit. O The central bright fringe becomes narrower, because the angle that locates the first dark fringe on either side of the central bright fringe becomes larger. O The central bright fringe becomes narrower, because angle that locates the first dark fringe on either side of the central bright fringe

m, and d= 3.00 x 10 m. (B) Determine the distance between adjacent bright fringes. Use the bright fringe equation again to find the distance between any adjacent bright fringes (here, those characterized by m and m + 1). AL AL (m+ 1) - AL Ay = y+1 m%3D (5.63 x 107 m)(1.20 m) - 2.25 cm 3.00 x 105 m LEARN MORE REMARKS This calculation depends on the angle 0 being small because the small angle approximation was implicitly used. The measurement of the position of the bright fringes yields the wavelength of light, which in turn is a signature of atomic processes, as is discussed in the chapters on modern physics. This kind of measurement therefore helped open the world of the atom. QUESTION Which of the following make the separation between fringes greater in the two slit interference experiment?

A sheet of metal has a large number of slits, each 5.0 mm wide and 20 cm apart. It is used as a diffraction grating for microwaves, producing bangs on a bulkhead. A broad parallel microwave beam is incident normally on the sheet. Considering c = 3.00 × 10⁸ m/s, answer the following two questions about this situation: a)What is the lowest microwave frequency for which only the central maximum occurs? 1 MHz 100 MHz 1.0GHz 2.0 GHz 1.5 GHz 500 MHz

If the spectrum on the screen is nearly continuous, with the exception of 3 small dark lines. Which of the following is most likely the light source?

In the figure, two isotropic point sources of light (S1 and S2) are separated by distance 3.20 µm along a y axis and emit in phase at wavelength 900 nm and at the same amplitude. A light detector is located at point P at coordinate xp on the x axis. What is the greatest value of xp at which the detected light is minimum due to destructive interference? y S2 Number i Units
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
In a Young's double-slit experiment, two rays of monochromatic light emerge from the slits and meet at a point on a distant screen, as in the drawing. The point on the screen where these two rays meet is the 8th-order bright fringe. The difference in the distances that the two rays travel is 4.16 × 106 m. What is the wavelength (in nm) of the monochromatic light? Number i Units €1 S1 하며 S2 Screen
