Monochromatic blue light with a wavelength of 483 nm falls on a single slit and produces a pattern with a central bright band that is 21 mm wide. The slit is located 94 cm from a screen. How wide is the slit?

A laser light source with wavelength λ = 545 nm is incident on a diffraction grating (as in the figure). The grating has 495 slits per mm. An observation screen is a distance L = 0.35 m from the grating. What is the separation between individual slits in the grating? Be careful with units: 1 nm = 10-9 m, 1 mm = 10-3 m, and 1 cm = 10-2 m. d = nm What is the distance y along the screen where the first-order diffraction peak is observed? y= cm source grating m=1

A screen is placed 50.0 cm from a single slit that is illuminated with light of wavelength 680 nm. If the distance between the first and third minima in the diffraction pattern is 3.00 mm, what is the width of the slit?

An instructor directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 550 nm and the slit is 0.230 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.65 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen?  Single-slit diffraction is most readily described with a formula that gives the distance from the center of the pattern to the mth-order dark fringe. Consider the first dark fringe on either side of the central peak  (m = ±1).  How does its distance relate to the full width of the central maximum? Take care with units. mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen?  Single-slit diffraction is most readily described with a formula that gives the distance from the center of the pattern to the mth-order dark fringe. Consider two adjacent fringes on one side of the…
