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?

Light is incident from air to glass at Brewster's angle. 1- Determine the incident and Transmitted angles. 2- Calculate the reflection coefficient for S-polarized. 3- Reflection coefficient for p- polarized.
Sydney wanted to color her hair from home so she signed up for an online service that sent hair color directly to her. The service required information about the thickness of Sydney's hair to mix the color properly. They only wanted to know if it was fine, medium, or thick, but being an astute student of physics, Sydney knew she could be more precise than that! She shone a red laser pointer with a wavelength of 670 nm through a single strand of hair and a diffraction pattern appeared on the wall 1.85 m away. a) Explain why this fringe pattern appears and how it confirms the wave nature of light. What would you predict the image on the screen to look like if light were a particle instead? b) What is the thickness of Sydney's strand of hair? Explain which formula is best to use here and why?
Imagine holding a circular disk in a beam of monochromatic light. If diffraction occurs at the edge of the disk, the center of the shadow is Question 9 options: the same as the rest of the shadow brighter than the rest of the shadow brighter or darker, depending on the wavelength brighter or darker, depending on the distance to the screen
II. Problem Solving. Show your step-by-step solutions. A transverse wave is propagating in a medium until it encounters another medium at an angle of incidence cqual to 30°. As a result, it refracts at an angle of 50° from the horizontal. What is its initial speed if its refracted wavclength and frequency are 0.02 meters and 5 Hz respectively?
