Waves Test Review PS.6 and Ps. 7 spr. 21

Wave Vocabulary Match the term to the definition Wave a disturbance that transfers energy from place to place Medium the material through which a wave travels Mechanical Energy examples are longitudinal and transverse waves Vibration repeated back and forth or up and down motion Wave Vocabulary Match the term to the definition transverse wave a wave that vibrates the medium at right angles (perpendicular) to the direction of the wave. crest high point on a transverse wave trough low point on a transverse wave longitudinal wave a wave that vibrates the medium in the same direction in which the wave travels (parallel) compression where the particles are close together rarefaction where the particles are far apart compression rarefaction wavelength longitudinal wave Part of a wave. Label the parts of the wave. crest amplitude wavelength trough transverse wave amplitude You have 3 headers for sorting. All descriptions will go under one of the headers. Sort each description under the correct header. Both Carries Energy Have frequency, speed, wavelength, and amplitude Have kinetic energy Mechanical Energy (KE) Longitudinal Waves Needs a Medium Particles of the medium move parallel to the wave Sound Waves Compression Waves Transverse waves Can travel through empty space (vacuum) Particles of the medium move perpendicular to the wave Light Waves Electromagnetic Waves Sound moves fastest in which medium. Solid Liquid Gas Vacuum Sound will have the greatest speed at which temperature. -20 degrees Celsius - 10 degrees Celsius 0 degrees Celsius 10 degrees Celsius A B EM Spectrum Label the EM Spectrum radio gamma ray Resonance is when vibrations traveling through an object match the object's natural_. speed frequency amplitude pitch The shattering of a glass by a singer and the collapse of the Tacoma Narrows Bridge are caused by_. reflection diffraction resonance refraction Matching Match the picture with the correct term Echolocation Sonar Sonogram Ultrasound Matching Match the term and definition Reflection Results from the bouncing back of a wave when it hits a surface that it can not pass through Diffraction The bending of a wave around the edge or a barrier Refraction The bending of a wave as it passes from one medium to another causing a change in its speed. Interference This is an interaction between waves. This is image shows that the angle of incidence and the angle of reflection are _. Unequal Different Equal Which wave has the greater frequency? A B t Which wave has the greater wavelength? A B Matching Match the term with the correct image. Reflection Refraction Diffraction Interference Constructive Interference Destructive Interference Increasing the wavelength of a wave will cause the sound to _. get softer get louder to have a lower pitch to have a higher pitch If you decrease the wavelength of a wave how will it impact the frequency and energy of the wave? The frequency would increase and the energy would decrease The energy and frequency would decrease The frequency would decrease and the energy would increase The energy and frequency would increase If you increase the amplitude of a wave, how will the sound be impacted? it have a lower pitch it will have a hight pitch the sound will be louder the sound would be softer The energy and frequency of a wave are directly related. This means same thing happens to each one. True False The frequency and wavelength of a wave are directly related. This means the same thing happen to each one. True False
