In a 2-slit experiment, one of the slits is covered by a thin film of refractive index n1 and the other slit is covered by another thin film of refractive index n2 (n1>n2). Both films have the same thickness t. A flat screen is located a distance L from the slits. The slit spacing is d. Find the shift in the position of the central maximum of the interference pattern because of the presence of the thin films.

Coherent light rays of wavelength strike a pair of slits separated by distance d at an angle 1, with respect to the normal to the plane containing the slits as shown in Figure P27.14. The rays leaving the slits make an angle 2 with respect to the normal, and an interference maximum is formed by those rays on a screen that is a great distance from the slits. Show that the angle 2 is given by 2=sin1(sin1md) where m is an integer.

(b) By what distance are the second and third maxima separated for l=486 nm?
In a realistic two‑slit experiment, you see two interference effects described in this chapter. There is the large‑scale interference pattern from diffraction that depends on the width of each slit, and within that pattern there is the small‑scale interference pattern that depends on the separation distance between the slits. For a slit width of 0.040 mm and a slit separation of 0.50 mm,what is the number n1 of bright two‑slit interference fringes that fit inside the central bright fringe of the diffraction pattern (from the first dark fringe on one side of the center to the first dark fringe on the other side) if the laser has a wavelength of 700 nm? n1 = ? For the same slit width and slit separation, what is the number n2 of bright two‑slit interference fringes that fit inside the central bright fringe of the diffraction pattern if the laser has a wavelength of 490 nm? n2 = ?
In a double slit interference experiment, the two slits are 0.3 mm apart. A laser beam of wavelength 621 nm, passes through the slits and an interference pattern is made on a screen that is 4.34 m away from the slits. Calculate the distance between the central bright fringe and the first side bright fringe. Write your answer in cm.
In a Young’s Double Slit Experiment the distance between two slits is 0.150 mm and the length from the double slit to the screen is 120 cm. The distance from central fringe to the nth fringe is 2 cm.
