Essential Question: How does data collected provide evidence that the amount of energy a wave carries determines the properties of a wave?
Waves Any disturbance that transmits energy through matter or empty space
Wave Energy Waves transfer energy through vibrations of particles in a medium. Medium- a substance through which a wave can travel. As a particle vibrates, it passes energy to the next particle.
Waves and Media Waves that need a medium to travel (mechanical): Sound Sound Ocean Ocean Seismic (earthquakes) Seismic (earthquakes) Waves that do not need a medium to travel (electro- magnetic) Light X-rays Microwaves TV and Radio
Types of Waves Waves can be classified based on the direction in which the particles in the wave vibrate compared to the direction the wave moves. 3 main types: Transverse Longitudinal Longitudinal Surface Surface
Transverse Waves The particles move perpendicular to the direction the wave is traveling.
Transverse Waves Continued. Crest- The highest point Trough- the lowest point
Longitudinal Waves Particles in the medium vibrate parallel to the direction of the wave motion.
Longitudinal Waves Continued Compression- particles are crowded Rarefaction- particles are spread apart
Sound Sound waves are a type of longitudinal wave that is the result of compressions and rarefactions of air particles.
Surface Waves Surface waves are a combination of transverse and longitudinal waves. Water Waves:
