Intro to Waves

1. How is a sound wave different from a light wave? 2. What happens when light is shined on an object? 3. What properties do all waves have? 4. How does the amplitude of waves help us understand light? 5. What is the relationship between the amplitude of a wave and the amount of energy it produces? 6. Give two examples of how sound waves interact with matter. Amplitude the greatest distance the particles in a wave rise or fall from their rest position Frequency the number of waves that pass a point in a given unit of time (crest to crest or trough to trough) Longitudinal Wave wave in which particles of the medium vibrate in the same direction that the wave travels (parallel) Reflection bouncing of a wave or ray off a surface Sound wave a compressional wave produced by vibrations Transverse Wave wave in which matter vibrates at right angles to the direction that the wave travels Trough Lowest point of a wave Wavelength the distance between a point on one wave to the same identical point on the next wave Crest Highest point of a wave To mark a word click its first letter then click its last.
