242 CHAPTER 6 POLARIZATION OPTICS 6.3-3 Double Refraction. An unpolarized plane wave is incident from free space onto a quartz crystal (ne = 1.553 and no = 1.544) at an angle of incidence 30°. The optic axis lies in the plane of incidence and is perpendicular to the direction of the incident wave before it enters the crystal. Determine the directions of the wavevectors and the rays of the two refracted components

In the macroscopic world, you know that you can hear but cannot see around corners. Under what conditions does light bend around corners (i.e. diffract) ? Explain why sound diffracts easily around a classroom door.

Physics - Unit: Applications of the Wave Nature of Light Many camera lenses are manufactured with a thin film over the glass to minimizereflection. Using diagrams and words, explain how this anti-reflective coating works.Discuss how the following variations will affect the properties of the anti-reflectivecoating.a. Changing the wavelength of lightb. Changing the angle of incidence of light

Question 1: X-ray Diffraction x-ray diffraction is a method used to identify different types of materials. While this is usually quite a complex process, however for a simple cubic structure, as seen below, we can find the distance between neighboring atoms. The below image shows the diffraction of x-rays passing through a cubic structure and illustrates a change in distance of 2d sine Light rays in phase ● a /I\ 100 20. b d sin 8 2d sin 0 Atoms in crystal If the wavelength of the x-ray is equal to an integer multiple of this change in distance, we will get constructive interference: mλ = 2d sine X-rays of wavelength 0.103 nm reflects off a crystal and a second-order maximum is recorded at a Bragg angle of 25.5°. (a) What is the spacing between the scattering planes in this crystal? (b) At what angle will the third-order maximum occur?
