Light from a 600 nm laser is shown through a single slit of unknown width. If a screen is placed 4.5 m behind the slit captures a diffraction patter with a central bright fringe of width 20 mm, what is the width of the single slit?

A slit 0.240 mm wide is illuminated by parallel light rays of wavelength 540 nm. The diffraction pattern is observed on a screen that is 3.00 m from the slit. The intensity at the center of the central maximum (u = 0°) is 6.00 x 10^-6 W/m2. (b) What is the intensity at a point on the screen midway between the center of the central maximum and the first minimum?

Monochromatic light of wavelength 592 nm from a distant source passes through a slit that is 0.0290 mm wide. In the resulting diffraction pattern, the intensity at the center of the central maximum (u = 0°) is 4.00x10-5 W/m2. What is the intensity at a point on the screen that corresponds to u = 1.20°?

A single-slit diffraction pattern is formed by monochromatic electromagnetic radiation from a distant source passing through a slit 0.105 mm wide. At the point in the pattern 3.25° from the center of the central maximum, the total phase difference between wavelets from the top and bottom of the slit is 56.0 rad. (a) What is the wavelength of the radiation?

A single-slit diffraction pattern is formed by monochromatic electromagnetic radiation from a distant source passing through a slit 0.105 mm wide. At the point in the pattern 3.25° from the center of the central maximum, the total phase difference between wavelets from the top and bottom of the slit is 56.0 rad. (b) What is the intensity at this point, if the intensity at the center of the central maximum is I0?

A single slit is illuminated by coherent monochromatic light at $680\mathrm{nm}.$ On a screen $2.9\mathrm{m}$behind the slit, a central bright spot is observed to have a width of $39\mathrm{mm}.$ What is the width of the single slit?

A carbon dioxide laser produceselectromagnetic waves, which pass through a circular aperture with diameter $1.0\mathrm{ mm}.$ What is the approximate width of the laser beam when it strikes a target $3.0\mathrm{ m}$away?

A single slit is illuminated by coherent monochromatic light at $680\mathrm{nm}$. On a screen $\mathrm{2..9}\mathrm{m}$ behind the slit, a central bright spot is observed to have a width of $39\mathrm{mm}$. What is the width of the single slit?

A single slit experiment is conducted in air using a laser at $532\mathrm{nm}$ and a slit width of $20\mathrm{\mu }\mathrm{m}$. What happens to the fringe spacing if the entire experiment is conducted in water?
