PPT-Section 16.6 The Interference of Waves from Two Sources (cont.)

2015 Pearson Education Inc Interference Along a Line If d 1 and d 2 are the distances from the loudspeakers to the observer their difference is called the pathlength difference. Wave Behavior. When waves encounter new mediums, barriers, or other waves they can behave in different ways. In physics these behaviors are described using some of the . following terms. .. Reflection. April 8 – April 9. Interference. Can two different objects occupy the . exact. same location at the . exact . same time? . Of course not … but two waves can! . When waves meet, they . superimpose . When printing this presentation, first save as Adobe .. pdf. . Then print the . pdf. .. This will ensure the output page fits A4.. DNA Structure. How did we work out the structure of DNA?. It is not just crystals that we can investigate with diffraction…. 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. Two pulses travelling in opposite directions will pass through each other unaffected. While passing, the displacement is simply the sum of the individual displacements. CP 514. SUPERPOSITION OF WAVES. 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. and the. Doppler Effect. Lecture 9. Pre-reading. : . §16.6–16.7. Wave Interference. Two or more traveling waves passing through same space at same time (identical frequencies). Use principle of superposition. Waves-3. resonance . clocks – pendulum . springs . harmonic motion . mechanical waves . sound waves . The periodic wave relation. Wave interference. standing waves. beats. musical instruments. 1. Review. Acoustical Beat. Periodic change in sound intensity caused by interference between two nearly identical sound waves. They occur when the frequency of the 2 waves is nearly identical. You hear beats as a change in loudness, from soft to loud. Copyright © 2014 John Wiley & Sons, Inc. All rights reserved.. 35-1. Light as a Wave. 35.01 . Using a sketch, explain Huygens’ principle. . 35.02 . With a few simple sketches, explain refraction in terms of the gradual change in the speed of a wavefront as it passes through an interface at an angle to the normal. . 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.. Associate Professor in Physics. Post Graduate Govt. College Sector-11. Chandigarh. Interference. The term interference refers to phenomenon involving superposition of waves leading to a modification of their intensity in the region of superposition.. Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth.
