A single slit of width W = 0.07 mm is illuminated by light that has a wavelength, = 680 nm.
a) Calculate the angles at which the first and the second dark fringe appears.
b) Using the small angle approximation (tan θ sinθ) find the relationship between the size of central maximum and the adjacent bright fringe.
c) Calculate the size of the central bright fringe if the screen is located 2.20 m away from the slit.
d) The single slit is now replaced with a diffraction grating and the second order bright fringe is formed at an angle of 23.0 with respect to the main axis. Find the number of lines per centimeter in the grating.

Light of wavelength 429 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.10 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). (a) Determine the distance y from the central bright fringe to the second-order bright fringe. (Hint: The diffraction angles are small enough that...
Light of wavelength 385 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.18 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). (a) Determine the distance y from the central bright fringe to the second-order bright fringe. (Hint: The diffraction angles are small enough that...
In a single-slit diffraction pattern on a flat screen, the central bright fringe is 0.9 cm wide when the slit width is 4.80 10-5 m. When the slit is replaced by a second slit, the wavelength of the light and the distance to the screen remaining unchanged, the central bright fringe broadens to a width of 2.1 cm. What is the width of the second slit? It may be assumed that θ is so small that sin θ ≈ tan...
ASAP PLEASE 2. Interference, 35 points 2.1, 25 points. A single slit is illuminated wit th 500mm mm light, and the If the B resulting diffraction pattern is viewed on a sereen 3m awa distance betwen the irst dark fringe and the central bright fringe ofcl pattern is 15cm, what is the width of the slit? 2.2, 10 points. Another slit of the same width is added at a distance d forming a two-slit set up. The two slits are...
In a single-slit diffraction pattern on a flat screen, the central bright fringe is 1.6 cm wide when the slit width is 2.8 × 10-5 m. When the slit is replaced by a second slit, the wavelength of the light and the distance to the screen remaining unchanged, the central bright fringe broadens to a width of 2.3 cm. What is the width of the second slit? It may be assumed that is so small that sin is approximately equal...
In a single-slit diffraction pattern on a flat screen, the central bright fringe is 1.6 cm wide when the slit width is 3.1 × 10-5 m. When the slit is replaced by a second slit, the wavelength of the light and the distance to the screen remaining unchanged, the central bright fringe broadens to a width of 2.0 cm. What is the width of the second slit? It may be assumed that is so small that sin is approximately equal...
