PPT-Color, Wavelength, and the Wider Electromagnetic Spectrum

Lesson 9 Parts of a Wave 1 second Which wave has the most energy How do you know evidence Step 4 Step 5 What is the relationship between energy and wavelength Red 780 nm Wavelengths of Color. Introduction To The Textbook. “Atomic Astrophysics and . Spectroscopy” (AAS). Anil . Pradhan. and Sultana . Nahar. Cambridge University Press 2011. Details at: . www.astronomy.ohio-state.edu/~pradhan/Book/book.html. LIGHT ENERGY IS ELECTROMAGNETIC IN NATURE. IT CAUSES A SENSATION OF VISION. ELECTROMAGNETIC RADIATIONS WHICH CAN EXCITE OUR RETINA HAS WAVELENGTH BETWEEN 8000 ANGSTROM TO 4000 ANGSTROM. ANGSTROM IS THE UNIT TO MEASURE WAVELENGTH.. (EMR). Remote Sensing Uses EMR!. Today’s learning objectives:. What is light and how do we describe it?. What . physical . units . do . we use to describe light?. Be able to convert between them and use scientific notation!. Almost all of our information on the heavens is derived from the light we see. We have returned samples from the Moon and a comet . Also obtained meteor samples. We have landed (with unmanned probes) on only a handful of planets and moons. Mrs. Molloy. 6. th. Grade Science. Electromagnetic Waves…. Do not need matter to transfer energy..

T. hink about the term “. electromagnetic. ”. . List as many things . that you can think of that are considered electromagnetic.. Electromagnetic energy. What is light?. Light is a wave: . Explains much of the everyday behavior of light. Light is a particle: . Explains why heated objects emit only certain frequencies of light at a given temperature. Light as Waves. 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.. “Atomic Astrophysics and . Spectroscopy” (AAS). Anil . Pradhan. and Sultana . Nahar.
