Wave - energy transfer that follows a repetitive pattern using matter or space as a medium., Mechanical Waves - Waves that need a medium of propagation., Transverse Wave - Transfer medium moves perpendicularly to direction of the wave. Always form high and low points in the transfer medium., Longitudinal Wave - Transfer medium moves PARALLEL to the direction of the wave. The medium moves at the same time in the same direction as the wave., Throughs - Low points of the wave., Crest - High points of the wave., Rarefaction - Stretching of other parts., Compression - Return to the original position., Wavelenght - Distance between one specific point in the wave and the nearest point occupying the same position in the next cycle., Disturbance - Sudden change cause by a wave., Amplitude - Measurement of how strong the disturbance caused by a wave., Cycle - part of the wave that extends until it repeats again., Frequency - Number of waves cycles that pass through a specific point in ONE SECOND., Wave period - amount of time needed for a cycle to pass through a point. Can be compare to a car race to complete a lab., Reflection - process through which a wave strikes an object or surface, and bounces back., Law of reflection - tell us that the angle at which a wave comes into contact with and strikes a surface is the same angle when it bounces off and moves away from that surface., Incident ray - Striking wave, Reflected ray - Wave that bounces off, Normal line - line right in the middle of the two rays., Echo - Result of sound waves reflecting back off a surface., Refraction - effect of a wave changing velocity as it passes from one medium to another., Diffraction - The waves bend. Waves pass around the object., Opaque - Not transparent., Radio waves - type of electromagnetic wave that can carry sound, images, and information., Wi-Fi - Wireless Fidelity.,
