PPT-Particles as waves

Particles as waves Aims understand that electron diffraction is evidence for wavelike behaviour use the de Broglie equation identify situations in which a wave model is appropriate and in which a particle model is appropriate for explaining phenomena involving light and electrons. . Bellringer. : What is A wave? (define, use Ch.22 in your book to help you). What is an example of a wave?. General definitions of vibrations and waves. Vibration. : in a general sense, anything that switches back and forth, to and fro, side to side, in and out, off and on, loud and soft, or up and down is . 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 . Section 9.1. Key Terms. Interference. Principle of Superposition. Constructive Interference. Destructive Interference. Wave Interference. Remember that waves are the result of particle vibrations.. Particles in a medium are connected by forces.. a short study of high school level understanding . By: Layla Quinones. New York University Department of Teaching and Learning. Background Information. Studies have shown that college students have difficulty describing wave phenomena due to misconceptions. S8P4. . 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 . The Van Allen Probes provide the first simultaneous multipoint measurements of these waves over broad regions. Powerful radio and plasma waves are central . to. the . acceleration and loss of radiation . 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 . 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?. A Physics MOSAIC. MIT Haystack Observatory RET. Revised 2011. Background Image from Wikipedia, Roger . McLassus. , Creative Commons . Reflection. When a wave encounters a boundary, it will be. at least partially reflected off this boundary.. 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 . 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 wave is any disturbance that transmits energy through matter or empty space.. Energy can be carried away from it’s source by a wave. As a wave travels, it does work on everything in it’s path. difference between mechanical waves and electromagnetic waves. . What is a wave?. A wave is a moving disturbance that transfers energy through matter or space. . Examples of waves. Water waves light waves. amplitude, frequency, wavelength, speed, phase, phase difference, . c . = . f . λ. . f . = . 1/. T . Phase difference may be measured as angles (radians and degrees) or as fractions of a cycle. . .
