PPT-Light Waves What is light?

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. Light:. Temperature, Scattering & Absorption. Essential Standards. 6.P.. 3 Understand . characteristics . of energy . transfer and interactions of matter and energy.. Clarifying Objectives. 6.P .. 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 . Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. Dennis Stewart. November.

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. . Seismic .

Waves transfer energy!. A wave does not carry matter . It only moves matter as it travels through it.. Waves. Compression (longitudinal) waves . are waves in which the particles of the medium move in a direction . Warm-Up: February 17/18, 2016. Vibrations and Waves. Chapter 14. A . periodic motion . repeats in a regular cycle.. Examples include:. Pendulums (such as on a grandfather clock). A mass at the end of a spring. Wave. Repeating disturbance or movement. Carries energy through matter and space. Vibrations. Anything that moves in a rhythmic patter. Up and down. Back and forth. What is a Wave. All waves are produced when something vibrates. 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.. Get 1 full page and 1 half page of paper. Fold full sheet of paper. about 1-1.5” short of even.

Wind waves move energy, not matter. Wind waves- Growth. Wind strength- must be moving faster than waves. Wind duration-longer creates larger waves. 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..
