Problem 3: A laser beam is incident on two slits with separation d = 0.034mm A screen is placed L = 4.8 m from the slits . The wavelength of the laser light is lambda = 3250A; theta_{1} and theta_{2} are the angles to the first and second bright fringes above the center of the screen. Part A: Express sin(theta_{1}) in terms of d and Part b solve for the numerical value of y in meters Part c Express the distance between the two bright fringes on the screen, in terms of e_{1}; theta_{3} and Part D Express sin(theta_{2}) in terms of d and

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.

Light with wavelength i passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distance d from the middle of the central maximum. Calculate the wavelength of light if D=3.1 m, d=1 mm and w = VAD. Give your answer in nanometers.

In an interference experiment using a monochromatic source emitting light of wavelength 1, the fringes are produced by two long, narrow slits separated by a distance d. The fringes are formed on a screen which is situated at a distance D >> d.Write down an expression for the fringe width w. Please use "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. Use "lambda" (without the quotes) for 1 in the equation box. For example, use d*lambda for d2. Please use the "Display response" button to check you entered the answer you expect. w=

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

Tries 1/3 Previous Tries Calculate the center to center spacing between the slits. Use the cm scale to measure distances on the screen. 2.25x10^-6 cm There is a fixed relation between wavelength, slit separation, and angle between the first (or second, third etc) order maximum and the central maximum. The angle can be determined from the distance to the screen and the separation between the first maximum and the central maximum on the screen. Submit Answer Incorrect.
