- Define Defraction.Discussion Question 2. How does the brightness of the internally reflected ray change when the incident angle changes from less than 0c to greater than 0c? Is the critical angle greater for red light or violet light? What does this tell you about the index of refraction?1. What are the function of each component in Figure 3?2. What is the differences of Phosporescence and Flourosecence?3. Why the profile of emission spectra look like the reflection profile of absorption spectrum? How to answer above questions based on picture drawing!
- 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?Please solve this problem for me and show work. It's a physics class!! FYI they are both sides are adding as you can see in the second picture. Thanks!!What colors of ink do color ink-jet printers us to produce a full range of colors? Do they form by color addition or by color subtraction?
- Explain retinex theory of color vision.Explain why soap bubbles has swirls of colors. Why are there different colors?P-3 Please help me with the below question with step by step explanation, please. NOTE: note that d is the perpendicular distance between the incident ray (pink solid line) and the pink dashed line
