Interference effects are produced at point P on a screen as a result of direct rays from a 490-nm source and reflected rays off a mirror, as shown in the figure below. If the source is L = 150 m to the left of the screen and h = 2.00 cm above the mirror, find the distance y (in millimeters) to the first dark band above the mirror. answer in mm

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…

You measure three segments of the distance between a diffraction slit an the screen on which the pattern forms: x1 = (15.8 ± 0.2) cm, x2 = (6.7 ± 0.1) cm, and x3 = (11.3 ± 0.1). What is the uncertainty of the total distance x1 + x2 + x3? Group of answer choices 0.4 cm 0.5 cm 0.2 cm 0.3 cm 0.1 cm

A slit of width 0.45 mm is illuminated with light of wavelength 544 nm, and a screen is placed 110 cm in front of the slit. Find the widths of the first and second maxima on each side of the central maximum. w1 =  mm (1st maxima) w2 =  mm (2nd maxima

A thin film of glycerin (n = 1.473) of thickness 475 nm with air on both sides is illuminated with white light at near normal incidence. What wavelengths will be strongly reflected in the range 300 nm to 700 nm? nm (smallest value) nm nm (largest value) Need Help? Read It

slit of width 0.46 mm is illuminated with light of wavelength 534 nm, and a screen is placed 114 cm in front of the slit. Find the widths of the first and second maxima on each side of the central maximum. w1 = mm (1st maxima) w2 = mm (2nd maxima)

A diffraction grating with n = 2.5E-05 lines/nm is used to separate two colors of light.
