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 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 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?

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 slit width is decreased while the distance to the screen and wavelength remain constant?

Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit covering a lens with a focal length of 60.0 cm. In the focal plane of the lens, the distance from the central maximum to the first minimum is 8.65 mm. What is the width of the slit?
