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. First a little . vocab. …. WAVE: . A periodic disturbance in a solid, liquid or gas. Some waves (light) can travel through empty space. MEDIUM:. Matter or space through which waves travel. I. Waves transfer energy. 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 . 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 . Learning Objectives. Know why light is said to travel in waves.. Know what polarisation is.. Know how diffraction patterns occur.. Success criteria. Explain how experiments show that light travels in waves. . Dennis Stewart. November. Smu. Modern Physics. 1. Outline for this talk. Einstein .

Explain the relationship among waves, energy, and matter. 2. Describe the difference between transverse waves and compressional waves. A. Waves Carry Energy. Waves (rhythmic disturbances that carry energy without carrying matter) can carry energy by itself or with matter. 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.. carries energy . through matter or space. . Water . waves, sound waves, and . the waves . that travel down a rope or spring are types of mechanical . waves. Mechanical . waves require a medium. .. A . 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.. LIGHT WAVES HIT THE LIGHT DETECTORNormally the light returns unchanged to the beam splitter from both arms and the light waves cancel each other outIf the arms are disturbed by a will have travelled d
