Nature of Waves Chapter 10.1
Wave Repeating disturbance or movement that transfers energy through matter or space Periodic motion What types of objects/source cause transfer of energy through waves?
Waves and Energy Waves carry energy not matter! Waves travel only as long as they have energy to carry Wave intensity decreases with distance from the original source of energy
Mechanical Waves Waves that travel only through matter Require medium (matter): Solid, liquid or gas Which of the following are mechanical waves? Sound Light Ocean Waves Seismic waves
Two types of mechanical waves Transverse Waves Matter in the medium moves back and forth at right angles to the direction that the wave travels Example: ocean waves Compressional (Longitudinal)Waves Matter in the medium moves back and forth along the same direction that the wave travels Example: coiled spring toys and sound waves
