PPT-Light Waves

The Electromagnetic Spectrum What is Light A difficult question thousands of years in understanding Very difficult to study since it cannot be caught and it is very difficult to measure What is Light. Light:. Temperature, Scattering & Absorption. Essential Standards. 6.P.. 3 Understand . characteristics . of energy . transfer and interactions of matter and energy.. Clarifying Objectives. 6.P .. Junior Science. Waves transfer energy. 1a. Waves are a means of transferring energy from one place to another without also transferring matter. Some waves need a medium (matter) to travel through and are known as . Dennis Stewart. November. Smu. Modern Physics. 1. Outline for this talk. Einstein . Einsteins Contribution. Joseph Weber. LIGO. The Machine and How it works. The Chrip. Conclusion. 2. Albert Einstein. Students will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . Electromagnetic Radiation. Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . Energy. Wave. Amplitude. Conduction. Convection. Radiation. Color spectrum. Wavelength. Potential energy. Kinetic energy. Light energy. Chemical energy. Mechanical energy. What is Energy?. “Energy” is defined as the ability to do work. Nature of science:. Imagination: It is speculated that polarization had been utilized by the Vikings through their use of Iceland Spar over 1300 years ago for navigation (prior to the introduction of the magnetic compass). Scientists across Europe in the 17th–19th centuries continued to contribute to wave theory by building on the theories and models proposed as our understanding developed.. Light. Light. Properties and Interactions. What is Light?. Light. is a form of energy emitted by the Sun..  . What is Light?. Light. is a type of energy that travels as an electromagnetic wave.. Gravitational Wave Bonus). The next slides show images of the SAME region of sky, but using different types of light. The view in VISIBLE LIGHT. INFRARED. RADIO WAVES. RADIO WAVES. GAMMA RAYS. Different types of light give us different information!. Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. inteferometer. . . Apparatus. :- . Spectrometer , monochromatic light, ultrasonic transducer, Rectangular cup containing test liquid. . .. . .. .. . Theory:-. . Ultrasonic interferometer is a simple device which yields accurate and consistent data, from which one can determine the velocity of ultrasonic sound in a liquid medium. . 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. At. a depth of ½ of the wavelength, the motion is not significant.. water. waves.... 4/5/2019. Physics 214 Fall 2010. 2. 1S-13 Slinky on Stand. Creating longitudinal compression waves in a slinky. What happens when you pull back and release one end of the slinky . ? . The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
