PPT-L4 Transverse Waves revisited-

Reflection Interference Standing Waves on String Transverse wave propagation Wave reflection at a fixed end the restoring force in the boundary material causes an upward pulse to become a downward pulse upon reflection. S8P4. Students will explore the wave nature of sound and electromagnetic radiation. . a. Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. Pages 8-12. 1. . A rhythmic . disturbance that carries energy but . not matter.. 2. A type of wave that can travel only through matter.. 3. Material through which a wave travels. This can be a solid, liquid, or a gas.. http://www.youtube.com/watch?v=JN3BQxSroGs. So what is a wave?. Is it energy?. Is it force?. A . Wave. is a disturbance that . transfers. . energy from one place to another without transferring . matter. Aaron Bunch. Abstract. The example of seismic waves in earthquakes leads us to expect that longitudinal and transverse waves will have different wave speeds in . a Slinky. . Using video analysis software, the speeds of longitudinal and transverse waves were measured in . 2. Waves are everywhere in nature. Sound waves, . visible light waves, . radio waves, . microwaves, . water waves. ,. stadium wave . . telephone chord waves, . . earthquake waves, . waves on a string, . General . Physics II . Topics covered: . Waves. Thermodynamics. Electricity. Magnetism. Currently . this corresponds to chapters 16 to 30 of . Fundamentals . of Physics. by Halliday, . Resnick. and Walker.. Waves. Waves. rhythmic . disturbances (vibrations) . that . transfer energy through matter . or. space . carry energy from one place to another. Very disturbing!. Waves. Water Waves. How does the video display what a wave is?. wave –. . disturbance that carries energy through matter or space. medium –. . matter through which a wave travels. the physical environment in which phenomena occur. mechanical wave –. . wave that requires a medium through which to travel. 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 . REMINDER!. DON’T FORGET. TO . STUDY!. . Electromagnetic waves. Mechanical waves. Interference. Reflection. Refraction. Pitch. diagrams. 1. Define . the following words:. Crest . – . the highest part of a transverse wave.. Before the waves are made the particles are same distance apart. While waves moves through the medium the particles . compress. together, then they spread further apart (stretched areas)- . rarefaction.. A. . B. . C. DO NOW TUESDAY. Give your own definition of a wave.. Learning Targets. 1.1a Define mechanical wave. . 1.2a Define electromagnetic wave. .. 1.3a Identify an electromagnetic . A. . B. . C. DO NOW TUESDAY. Give your own definition of a wave.. Learning Targets. 1.1a Define mechanical wave. . 1.2a Define electromagnetic wave. .. 1.3a Identify an electromagnetic . Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant..
