The nonreflective coating on a camera lens with an index of refraction of 1.31 is designed to minimize the reflection of 600-nm light. If the lens glass has an index of refraction of 1.55, what is the minimum thickness of the coating that will accomplish this task? m

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…

Q1:a) Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit covering a lens with a focal length of 60.0 cm. In the focal plane of the lens the distance from the central maximum to the first minimum is 10.2mm. What is the width of the slit? b) Unpolarized light of intensity 20 W /cm² is incident on two polarizing filters. The axis of the first filter is at an angle of 25.0° counterclockwise from the vertical and the axis of the second filter is at 62.0°counterclockwise from the vertical. What is the intensity of the light after it has passed through the second polarizer?
