Hi, I need help with the following question. Could you pleaseshowyour work so that I may better understand how the solutionwasachieved? Thanks!

Upper plane d Lower planeUsethe figure as a reference for problems (1) and(2)

(1)Potassium iodide has a crystalline structure with atomicplanesseparated by 0.353 nm. A monochromatic x-ray shows afirst-orderdiffraction maximum when the grazing angle is7.60°.
a) Calculate the x-ray wavelength
b) Assume now that the x-ray is observed at an incident angleof31.9°. Will constructive interference occur? (Defend yourargumentcalculatively)

(2) Assume 0.140 nm x-rays are diffracted on aninterplanarspacing of NaCl, which is 0.281 nm.

a) What is the predicted angle in the first-order?

b) What is the predicted angle in the second-order?

c) What is the maximum order for reflection? Why?


1) On the plane mirror system shown here, if thefinalangle
of reflection for this ray is 14.0°, find the initial angleofincidence.
2)

A ray oflight is sent between parallel planemirrors, as shown.The raybarely misses the lower mirror as itenters the“corridor.” The mirrors' edges are aligned withoneanother, as shown. The mirrors are 3.00 cm apart, and each is18.0cm long. Find the smallest initial angle of incidence so thattheray…

(ii)hits each mirror exactly once.

3) Why don't diamonds sparkle as much when viewedunderwater?Explain thoroughly,using words, equations and diagramsasnecessary.
4) A spherical mirror producesan image that is located 43.0 cmbehind the mirror when the objectis located 12.5 cm in front ofthemirror.
(i)What is the focal length ofthemirror? (ii)Isthis mirror concave orconvex?
5)A concave mirror (f= 54.0 cm) produces a real imagewhose distance from themirror is one-third of theobjectdistance. (i)Findtheobjectdistance. (ii)Findthe imagedistance.

1. Write at least one paragraph in which you define diffraction andinterference, discuss Huygens' Principle and explain why lightpassing through a narrow slit or set of fine slits will produce apattern on a wall.
2. Diode lasers produce a range of wavelengths. Do you think usingthe average made much difference in your calculations? Explain indetail.
3. How would the pattern on the wall have been different if you hadused a helium-neon laser which only produces light of onewavelength?
4. What would the diffraction pattern look like if the light youused was composed of several specific wavelengths?
5. In order to have a clear diffraction pattern the slit must bearound the same order of magnitude as, but not smaller than thewavelength of the light. What is the ratio of single slit width towavelength for your experiment? How would the pattern on the wallchange if you could gradually widen the slit?
Please show me step by step, thank you so much for your help
