Four trials of Young's double-slit experiment are conducted.

(a) In the first trial, blue light passes through two fine slits 400 μm apart and forms an interference pattern on a screen 4 m away,

(b) In a second trial, red light passes through the same slits and falls on the same screen.

(c) A third trial is performed with red light and the same screen, but with slits 800 μm apart,

(d) A final trial is performed with red light, slits 800 μm apart, and a screen 8 m away.

(i) Rank the trials (a) to (d) from the largest to the smallest value of the angle between the central maximum and the first-order side maximum. In your ranking, note any cases of equality,

(ii) Rank the same trials according to the distance between the central maximum and the First-order side maximum on the screen.

Monochromatic light of wavelength λ is incident on a pair of slits separated by 2.40 × 10−4 m and forms an interference pattern on a screen placed 1.80 m from the slits. The first-order bright fringe is at a position ybright = 4.52 mm measured from the center of the central maximum. From this information, we wish to predict where the fringe for n = 50 would be located. (a) Assuming the fringes are laid out linearly along the screen, find the position of the n = 50 fringe by multiplying the position of the n = 1 fringe by 50.0. (b) Find the tangent of the angle the first-order bright fringe makes with respect to the line extending from the point midway between the slits to the center of the central maximum. (c) Using the result of part (b) and Equation 36.2, calculate the wavelength of the light

Two finite-width slits are illuminated by a parallel beam of lightof wavelength 635 nm. The resulting pattern is observed on a screenat a distance of 1.60m from the slits. The central brightdiffraction fringe has a width of 4.20 cm. It is observed that thefourth interference maximum on either side is missing.
(a) What is the width of each slit?
(b) What is the distance between the slits?
(c) What other interference maxima (if any) are missing?
(d) Sketch the intensity as a function of distance from the centerof the pattern.
(Your sketch should include three bright diffraction fringes, thecentral one and the first one on either side.)
