Waves
Properties of Waves Watch the video to review waves. A _ is any disturbance that transmits energy. Transverse wave Wave Mechanical wave Longitudinal wave _ waves travel in an up-and-down fashion. Mechanical wave Longitudinal wave Transverse wave Wave _ waves move in compressional pulses (back-and-forth) Longitudinal wave Transverse wave Mechanical wave Wave _ waves NEED a medium (ex. sound waves) Transverse wave Electromagnetic wave Mechanical wave Longitudinal wave _ waves do NOT need a medium (ex. light waves). Transverse wave Electromagnetic wave Mechanical wave Longitudinal wave Which type of wave is this? Transverse Longitudinal Both Neither Which type of wave is this? Transverse Longitudinal Both Neither Label the Wave Label each part of a transverse wave, using the following words in lower case letters:crest, trough, rest position, amplitude, wavelength. wavelength amplitude rest position crest trough Match It Up! Match each term to the correct definition. The height of a wave. amplitude The distance between two crests and two troughs. wavelength The number of waves in a given time period. frequency The speed at which a wave travels. wave speed The highest point on a wave. crest The lowest point on a wave. trough Sort It Out! Sort the characteristics under each type of wave. Transverse Waves Also called electromagnetic waves Movement is up and down An example is light Travel perpendicular to the medium Can travel through a medium or a vaccuum Longitudinal Waves Also called mechanical or compression waves Movement is back and forth An example is sound Travel parallel to the medium Can only travel through a medium Search the Word!
