Measuring distances to high precision is a critical goal in engineering. Numerous devices to exist to perform such measurements, with many involving laser light. Shining light through a double slit will provide such a ruler if (1) the wavelength of the light beam and slit separation is known and (2) the distance the minima/maxima appearing on the screen can be measured. But this in itself requires a physical measurement of distance on the object, which may not be practical. In an effort to create a \"laser-beam ruler\" that does not require placing a physical ruler on the object, you mount a Nd:YAG laser inside a box so that the beam of the laser passes through two slits rigidly attached to the laser. Although 1064 nm is the principal wavelength of a Nd:YAG laser, the laser is also switchable to numerous secondary wavelengths, including 1052 nm, 1075 nm, 1113 nm, and 1319 nm.

PART 2: Multiple slits - Interference Remove the single slit disk, and install the multiple slit disks. You will now sements as in part 1 to explore the nature of the multiple slit interference patit this case, however, you will mark the maxima, not the minima. Siit disks. You will now do much the same Use the double slits of separation d = 0.25 mm (and a = 0.04mm). Increase distance L ben the screen and the slit as much...
Can you answer the multiple choice all 1-7? The focal length of a converging leas is determined through image formation Assuming an object distance of 105 cm and an image distance of 10 cm. what is the focal length of this lens? 5 A) infinity B) 11 cm C)9.13cm D)0.1095mm A light ray traveling in air is incident on the surface of a glass plate The light ray makes an angle of 32 degree with the normal to the surface,...
Note: This test contains ten questions from chapter 19 to chapter 27. For full credit, you should show all the steps of your numerical answers. No credit would be earned for just circling the right answers. Chapter 19 - Electric Potential and Electric Potential Energy 1. Two point charges are of + 7 uC and - 4 C are held at the corners of a rectangle as shown. The lengths of the sides of rectangle are 0.15 m, and 0.05...
