Name_______________________________________ Wave Notes S8P4. a. Ask questions to develop explanations about the similarities and differences between electromagnetic and mechanical waves. Waves— • Any ______________________ that transmits _______________ Electromagnetic Waves— • Waves that do not need a ________________—a substance through which the wave can ________ • Can travel through a _______________ Ex. light, __________________, TV &Radio waves, _______________ Mechanical Waves— • Waves that need a _______________—a __________________ through which the wave can travel (___________, ____________, ______________) Ex. _____________ waves, _____________ waves, Waves travel as either Transverse or Longitudinal Waves Transverse Waves— • Waves move __________________ to the direction the wave is traveling • highest point—______________ • lowest point—______________ Longitudinal waves— • Waves move _________________ to the direction the wave is traveling • crowded areas—____________________ • spaced out areas—____________________ S8P4. f. Develop and use a model (e.g., simulations, graphs, illustrations) to predict and describe the relationships between wave properties (e.g., frequency, amplitude, and wavelength) and energy. Parts of the wave— Crest—the _____________ point of a transverse wave Trough—the _____________ point of a transverse wave Wavelength—the distance from any point on one ___________ to an __________________ point on the next wave Amplitude—the maximum _________________ that the particles of a __________________ vibrate from their rest position (the _______________ of the wave) Name_______________________________________ Remember: AL Amplitude/loudness PF Pitch/frequency 1) The amplitude of a wave is related to _______________. 2) The greater the amplitude the _______________ the sound and the more _________________ it has. This wave will sound ____________________ This wave will sound ___________________ Frequency—the ________________ of waves produced in a given amount of ____________ The frequency of a wave determines _______________ and _______________. A wave with a ___________ frequency has a high pitch and ______________ energy. A wave with a ___________ frequency has a low pitch and ______________ energy. This wave would have a ___________ pitch. This wave would have a ___________ pitch. Name_______________________________________ The higher the
