Consider the conceptual physics behind the visual process. Explain how
Question Consider the conceptual physics behind the visual process. Explain how the curves of the cornea and the lens relate to the angle of light wave projection. Describe some of the changes or problems in the eye structure that can cause a problem with vision. Describe some of these problems and the way they alter or block light waves. For example, cataracts obstruct light waves, thereby causing problems with vision.Describe the role of photoreceptors and their location in the eye.Explain the importance of locations to other cells in the retina and the influence on light waves. The optic nerve produces a blind spot in our visual field. Explain how the knowledge about the blind spot and our lack of awareness teach us about the perceptual process.

An electron begins in the n=5 energy level in the
Question An electron begins in the n=5 energy level in the Hydrogen atom. It then loses some energy, falling to the n=2 energy level. Since the electron is still not in the most stable energy state, it then loses energy and falls into the n=1 energy level.A. What is the wavelength of the photon emitted during the n=5 to n=2 transition?B. What is the energy of the photon emitted during the n=2 to the n=1 transition?C. What is the deBroglie wavelength of an electron traveling at a speed of 0.8 c?D. If you replace the electron in the previous question with a proton traveling at a speed of 0.8 c, how would the deBroglie wavelength change?(proton’s wavelength smaller or larger than electron’s wavelength?)Please show formula and work and give reasoning for D.
