A beam from a krypton ion laser (gamma = 461.9 nm) falls on a single slit, producing a central maximum 4.0cm wide on a screen 1.50m away. a. Calculate the slit width b. Determine the angle between the rays travelling to the 2nd minima and the rays travelling to the central maxima.

The headlights of a car are 1.5 m apart. Your pupil has a diameter of 5 mm, and the wavelength of the light from the headlights is 600 nm. a. If the car is 50 m away from you, what is the angle between the headlights? b. Can you tell whether the car has two headlights or one?  c. What is the maximum distance at which you would still be able to resolve headlights? d. The pupil of your eye changes size depending on how much light it is exposed to. If the diameter of your pupil increased from 5 mm to 7 mm, would your answer in part (c) get larger or smaller?

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…

The nonreflective coating on a camera lens with an index of refraction of 1.23 is designed to minimize the reflection of 625-nm light. If the lens glass has an index of refraction of 1.51, what is the minimum thickness of the coating that will accomplish this task? X Your response differs from the correct answer by more than 10%. Double check your calculations. m

The lens of a telescope has a diameter of 25 cm. You are using it to look at two stars that are 2 × 10 17 m away from you and 6 × 10 9 m from each other. You are measuring light with a wavelength of 700 nm. As the light goes through the lens, it diffracts. a. Is it possible, using this telescope, to see the two stars as separate stars?  b. What is the minimum possible lens diameter you would need in order to resolve these two stars?
