PPT-Sound, Light, Electromagnetic Spectrum and Mirrors

Sound Sound waves are compressional waves Two regions compressions and rarefactions Sound travels faster in liquids and solids than in gases Why The molecules in liquids and solids are closer together. Section . 1- What . are electromagnetic waves?. WHAT DO CORDLESS PHONES AND MICROWAVE OVENS HAVE IN COMMON?. Each emits electromagnetic waves.. Remember…. A . wave. . is a repeating disturbance or movement that transfers energy through matter or space.. 14.1: Mirrors. I. Plane Mirrors. Flat, smooth mirro. r. Creates a . virtual image. : an image your . brain. perceives even though . no light rays pass through it. .. Image appears . upright. and as far behind the mirror as the object is in front of it (same size as object).. Mrs. Molloy. 6. th. Grade Science. Electromagnetic Waves…. Do not need matter to transfer energy.. Made by vibrating electric charges.. Travel by transferring energy between electric and magnetic fields.. 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. Energy that travels as a wave through space. Wavelength –. λ – distance between corresponding points on adjacent waves. Frequency – f – waves per second. Spectrum.

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. 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. Waves. What is a wave?. A wave is a disturbance that travels from one location to another location. The traveling disturbance in a wave is carrying energy (NOT matter). Waves that require a medium to travel through are . Presented By. Dr. . Banashree. . Saikia. Assistant Professor. Department of Geography. JN . College, . Boko.

Electromagnetic Wave overview. Wave Overview. Spectrum Overview. Particle and Wave Properties. Speed equations. Light. Science. . . Success Criteria. Aim. I can use a mirror to reflect light and explain how mirrors work. . I can explain why mirrors are good reflectors.. I can use mirrors to reflect light onto different objects.. 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..
