Section 372 DoubleSlit Interference Section 373 MultipleSlit Interference and Diffraction Gratings Problem Problem 3 doubleslit experiment spacing 012 mm should be 13 In. Huygen’s Principle. Any wave (including electromagnetic waves) is able to propagate because the wave . here . affects nearby points . there. In a sense, the wave is the source for more of the wave. Textbook sections 28-4 – 28-6. Physics 1161:. . . Lecture 21. Recall. Interference . (at least 2 coherent waves). Constructive (full wavelength difference). Destructive (½ wavelength difference). Has wave properties.. Can diffract.. Can constructively or destructively interfere. .. Coherent Light. A beam of light that has the same frequency, wavelength, phase, and direction is called . coherent. Introduction to Physics II. . Class 5 – . Outline:. Ch. . 22, . sections . 22.1-22.4. (Note we are skipping sections 22.5 and 22.6 in this course). Light and Optics. Double-Slit Interference. The Diffraction Grating. Wave Optics. The wave nature of light is needed to explain various phenomena. Interference. Diffraction. The . particle nature of light was the basis for ray (geometric) . optics. Light waves interfere with each other much like mechanical waves do. Pg. 459 - 461. Properties of Waves. In order to study the properties of waves, a ripple tank is used. A shallow, glass-bottomed tank on left. ~2cm of water is added. Light from a source above the tank passes through the water and illuminates a screen on the table below. Up to now we have been studying . geometric optics. . Today we will look at effects related to the . wave nature of light –. . physical optics. polarization. interference. thin film interference. Up to now we have been studying . geometric optics. . Today we will look at effects related to the . wave nature of light –. . physical optics. polarization. interference. thin film interference. not . from pigmentation (dull brown) but from interference in small structures on the wings. 200 . micron . scale photo. 1. Incandescent bulb viewed through a diffraction grating.. Office Hours: I am available before class 11:30-12:10 MWF and after class on Monday and Friday in WAT 233 and by arrangement (. Dr. Quantum. 27.1 . The Principle of Linear Superposition. When two or more light waves pass through a given point, their electric. fields combine according to the principle of superposition.. The waves emitted by the sources start out in phase and arrive at . Learning Goals for Chapter 36. Diffraction. vs. . Interference. Single-slit vs. Multiple-slit diffraction. Calculating intensity . at . points . in . single-slit pattern. .. X. -ray . diffraction reveals . Physics . 2212. Light. Light has Wave properties. Light can Diffract. Light can Interfere. Constructively. Destructively. Wave Fronts. Lines that are perpendicular to the motion of the wave, indicate the location of the crests in the waves that are traveling together.. Bellringer – 2 . mins. to hand in. Describe why you think rainbows sometimes pop up after it rains.. DO WORK. STOP. Objectives. Be able to fully explain exactly how rainbows, sunsets, sunrises, polarization, and diffraction work.. 1. Prelude to matter duality. Relativity (we’re trapped in 4D). The Quantum World. Implications of the Quantum Reality. The Discovery Frontier. “First. , we cannot find any clicker responses for the last two questions of session 3 for your course. There isn't anything else we can do here and you will need to throw out the last 2 questions in Session 3 to be fair to the clicker users. .
