Calculate the thickness of a film of a soap bubble, for which, backscattered light has been used that produces a maximum of interference with light of 600 nm and a minimum with light of 400 nm. Assume the refractive index of the soap film to be identical to that of water. The important assumption is that the curved surface is considered to be flat.
Two in-phase coherent sources S1 and S2 are placed at positions rsı = (L, 0) and rs2 = (0, L), with L = 24 m (as shown in the diagram). The sources emit waves of wavelength 11.5 m.

Two beams of coherent light from the same source travel different paths, arriving at point P. If completely destructive interference is to occur at point P, which of the following could be the path difference between the two waves? оооо о The path difference between the two waves could be one-quarter of a wavelength. The path difference between the two waves could be one wavelength. The path difference between the two waves could be two and one-half wavelengths. The path difference between the two waves could be one-half of a wavelength. The path difference between the two waves could be two wavelengths.
When light passes through sequential interfaces, there may be a change of phase upon reflection at each interface. Additionally the wavelength changes with each change of the index of refraction. If the thickness of a thin layer is chosen correctly, then it will serve as an anti-reflective coating bringing about maximally destructive interference between the first and second reflected waves.For convenience, the index of refraction for a variety of materials is provided below.

What is the minimum possible thickness of the film? the incident light is white light Again, although the rays have not been drawn perpendicular to the interface, that is just for clarity.

A perfectly flat piece of glass (n = 1.50) is placed over a perfectly flat piece of black plastic (n = 1.20) as shown in the figure a. They touch at A. Light of wavelength 600 nm is incident normally from above. The location of the dark fringes in the reflected light is shown on the sketch of figure b.

How many dark fringes are seen when all the air has been displaced by water? (The straightness and equal spacing of the fringes is an accurate test of the flatness of the glass.)

The following problem must be solved taking into consideration the modification given below: A student holds a laser that emits light of wavelength 545 nm. The laser beam passes though a pair of slits separated by 0.500 mm, in a glass plate attached to the front of the laser. The beam then falls perpendicularly on a screen, creating an interference pattern on it. The student begins to walk directly toward the screen at 2.00 m/s. The central maximum on the screen is stationary. Find the speed at which the 5th-order maxima changes its position on the screen. Do not use small angle approximation. Modification: Suppose there is a liquid in the space between the slits and the screen. Give such liquid any refractive index you desire (numerical value). Also suppose that the screen has a finite lenght (give another numerical value). Besides calculating the speed at which the 5th-order maxima changes its position on the screen also calculate the initial value of bright fringes according to the…
