The electromagnetic spectrum can be divided into several bands based on the wavelength. (Insomecircumstances, lighthas This preview shows page 1 - 2 out of 4 pages. Properties of light 1. Read the descriptions to the left and answer each question on the right. These objects are called translucent objects. Medium Speed (m/s) Refractive index Vacuum 3 x 108. (such as waxed paper) • transparent: Allows almost all light to go through, so can be seen through clearly. • How do we measure it? 64-71, 103-114 (5.3 is optional). Physical properties of light Light consists of photons — “particles” with no mass which travelatthespeedoflight. The information is based on many laboratory studies and records of a large number of existing structures that have provided satisfactory service for more than 85 years. Depending on the type of matter it comes into contact with, light will behave. Today scientists say light is a form of energy made of photons. 64-71, 103-114 (5.3 is optional). This energy is both (1) magnetic and electrical. by Ted Adelson Properties of light Today • What is light? hެ�m��8���?��D��8q� As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm. This confusion about the true nature of light continued for some years till a modern quantum theory of light emerged in which light is neither a ‘wave’ nor a ‘particle’ – the new theory reconciles the particle properties of light … CHAPTER 6 PHYSICAL PROPERTIES OF STRUCTURAL LIGHTWEIGHT CONCRETE This chapter covers some of the physical properties of lightweight concrete. light, we would be unable to see anything! • Watt & Policarpo, The Computer Image, Addison-Wesley, 1998, pp. light with matter, and light often behaves somewhat like a stream of particles. Light can also be described in terms of a stream of photons, massless packets of energy, each travelling with wavelike properties at the speed of light. Toaverygoodapproximation, lighttravelsinstraightlines, and behavesmuchlikeaparticle. The speed of light will change as it passes through different substances. through objects such as solids or liquids. At any point on the path of a simple harmonic light wave the strengths of the electric and magnetic fields are continually changing. 2There are many different types of electromagnetic (EM) waves. 129 0 obj <>stream Other objects completely reflect light, like an, animal or a book. BRIGHT ART CHALLENGE Objectives • Learn about light energy and the electromagnetic spectrum • Learn the properties of light • Review the parts of a wave • Discover the relationship between brightness and amplitude, color and frequency MSPS4-2 Vocabulary • light • light … Reflection incident ray reflected ray Normal Surface 4.
