PHY: DIFFRACTION AND INTERFERENCE
Pre-Lab:
1) Two narrow slits, 50?m apart are illuminated with 500 nm ligh. What is the angle of the m =2 bright fringe in radians? In degrees?
2) Light from a helium-neon laser (? = 633 nm) passes through a circular aperture and is observed on a screen 4.0 m behind the aperture. The width of the central maximum is 2.5 cm. What is the width of the hole in mm?
3) What is the width of the slit for which the first minimum is at 0.45° when the slit is illuminated by a helium-neon laser (? = 633 nm)?

Light from a Helium-Neon laser (λ = 633 nm) is incident on a regular array of slits with a slit spacing of a = 1.50 μm and an interference pattern is seen on a screen placed a distance of D = 4.50 m away from the slits, at what distance y from the center of the pattern will the first bright fringe occur? A) 2.10 m B) 3.60 m C) 1.20 m D) 2.40 m
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.60 m behind the slit. The distance between the first and second minima in the diffraction pattern is 4.15 mm . What is the width (in mm) of the slit?
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.30 m behind the slit. The distance between the first and second minima in the diffraction pattern is 3.95 mm .What is the width (in mm) of the slit?
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.60 m behind the slit. The distance between the first and second minima in the diffraction pattern is 3.65 mm. What is the width (in mm) of the slit?
Light at 633 nm from a helium–neon laser shines on a pair of parallel slits separated by 1.45 x10^-5 m and an interference pattern is observed on a screen 2.00 m from the plane of the slits.

Modern Optics, Eugene 5th Edition 1. You pass 633-nm laser light through a narrow slit (single-slit) and observe the diffraction patter on a screen 6.0 m away from the slit. You find that the displacement on the screen between the centers of the first minima on both sides of the central bright fringe is 32.0 mm. Find the width of the slit.
2. (10 points) A real (non-ideal) double-slit slide is illuminated by blue laser light with a wavelength of 450 nm. The slits are spaced 0.25 mm apart. The interference pattern is observed on a screen 2.0 m behind the slits, and you notice that every 5ih bright fringe is missing. How wide are the slits? (You may assume the small angle approximation is valid here.)
