Problem 13: Two slits are illuminated by a 340 nm light. The angle between the zeroth-order bright band at the center of the screen and the fourth-order bright band is 13°. a) If the screen is 130 cm from the double-slit, how far apart is this bright band from the central peak? b) What is the distance between the two slits?

Two slits separated by 0.10 mm are illuminated with green light (2 = 540 nm). Calculate the distance (in cm) from the central bright-region to the fifth bright band if the screen is 1.0 m away. O 2.1 2.7 O 2.5 2.3 2.0

Narrow, equally spaced vertical slits with equal widths are located at a distance of D = 2.47 m from a screen. The intensity pattern in the figure is observed when light with wavelength = 570 nm from a laser passes through the slits, illuminating them uniformly. The screen is perpendicular to the laser beam. 0 1 2 3 4 5 6 7 8 9 cm 7 The number of slits is ... Submit Answer Incorrect. 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. Tries 1/12 Previous Tries Calculate the width of the slits. Use the cm scale to measure distances on the screen. Submit Answer Tries 0/12

A double slit experiment is performed where the two slits are separated by 0.134 mm. Visible light of 532 nm passes through the slits and falls onto a screen 4.00 m from the slits. a) What is the distance along the screen from the central maximum to the nearest minimum? ________________________ b) What is the angular position (in degrees) of the third-order maximum, relative to the central maximum? ________________________ c) What are some other wavelengths of light that would have maxima located at the same position as the third-order maximum for 532 nm light? List at least four wavelengths, along with the order of the maximum, and the type of light (visible, infrared, etc). Note that UV is from 10-380 nm, visible is from 380-750 nm, and IR is from 750 nm – 1 mm. Wavelength Order Type of light

This question is regarding the experiment ’Diffraction and Interference of Light’. a) In a diffraction experiment for a given slit and a given slit-screen distance,would the distance between the dark fringes increase or decrease when a blue laser is replaced with a red laser? Use equations to argue why, in no more than two sentences (Hint: wavelength λblue = 470nm, λred = 700 b) Draw the pattern you observe for two slit interference. Mark clearly the diffraction and the interference parts of this pattern. c) How will the pattern change? When I change the distance between the slits?
