A. Find the angle (in degrees) of the second diffraction minimum for 750 nm light falling on a slit of width 28.0 µm. B.What slit width (in µm) would place this minimum at 80.0°?

Laser light of wavelength 627.0 nm passes through a double-slit arrangement at the front of a lecture room, reflects off a mirror 29.2 m away at the back of the room, and then produces an interference pattern on a screen at the front of the room. The distance between adjacent bright fringes is 9.52 cm. What is the slit separation in meters? Number i 0.000192 Units m

Green light (λ = 546 nm) strikes a single slit at normal incidence. What width slit will produce a central maximum that is 2.75 cm wide on a screen 1.80 m from the slit?

Light with a wavelength of λ = 605 nm is incident on a single slit of width w = 2.25 micrometers. A screen is located L = 0.65 m behind the slit and an interference pattern has formed on it. a) What is the distance between the central bright spot and the first dark fringe, D, in meters?

Light is sent through a single slit of width w = 0.52 mm. On a screen, which is L = 1.9 m from the slit, the width of the central maximum is D = 5.2 mm. a) The angle of the first dark fringe theta dark. Express sin(theta dark) in terms of the wavelength of the light λ and w. sin(theta dark) =  b) Express tan(theta dark) in terms of D and L. c) If D << L, how is tan(theta dark) related to sin(theta dark)? d) Express λ in terms of w, D, and L? e) Solve for the numerical value of λ, in nanometers.

In a double-slit experiment, coherent light of wavelength 545 nm is incident upon two slits that are separated by 0.434 mm. The fringe pattern is viewed on a screen that is 2.32 m away. What is the width of the central maximum on the screen? Give your answer in cm.
