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 Waves 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 You have 2 headers for sorting. All descriptions will go under one of the headers. Sort each description under the correct header. Sound Waves Needs a Medium Particles of the medium move parallel to the wave Mechanical Wave Contains compressions and rarefactions Light Waves Can travel through empty space (vacuum) Particles of the medium move perpendicular to the wave Electromagnetic Waves Contains crests and troughs Sound moves fastest in which medium. Solid Liquid Gas Vacuum 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 Which wave has the greater wavelength? A B Matching Match the term with the correct image. Reflection Refraction Diffraction Interference Constructive Interference Destructive Interference 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 higher pitch the sound will be louder the sound would be softer Which of the following is NOT a medium through which a mechanical wave can travel? solid vacuum gas liquid Which of the following is transferred during the movement of a wave? speed mass matter energy Which of the following is NOT a type of electromagnetic wave? radio waves microwaves sound waves ultraviolet waves For a wave, the _ the amplitude, the _ energy the wave carries. larger, more smaller, more larger, less smaller, more What is the wavelength of Wave A? 2 m 4 m 6 m 8 m What is the wavelength of Wave B? 2 m 4 m 6 m 8 m What is the amplitude of Wave A? 5 m 10 m 15 m 20 m What is the amplitude of Wave B? 5 m 10 m 15 m 20 m Which wave has the greater frequency? Wave A Wave B Which wave has the least amount of energy? Wave A Wave B A mediumis a material through which waves can travel. It can be a solid, liquid, or gas.Frequencyis the measure of how many waves pass a point in a certain amount of time.Absorptionoccurs when the energy of a wave is not transferred through, or reflected by, the given medium.Amplitudeis a measure of the distance from the resting point of a wave to a crest or trough.Wave speedis a measure of the distance a wave travels in an amount of time.Wavelengthis the measure of the distance from crest to crest or trough to trough of two consecutive waves. Which occurs when the crest of one wave overlaps the trough of another wave? constructive interference wave cancellation amplitude shift interference destructive interference Which occurs when the crest of one wave overlaps the crest of another wave? constructive interference wave cancellation amplitude shift interference destructive interference In the figure shown, the light waves change direction as a result of _. diffraction reflection refraction reverberation In the figure show, if angle i increases slightly, angle r will _. decrease disappear increase remain the same Parts of a Wave Label the parts of the wave. Use the terms rarefaction, compression, wavelength. Also identify the type of wave. Compression Rarefaction Wavelength Longitudinal Part of a wave. Label the parts of the wave. Use the terms crest, trough, amplitude, rest position and wavelength. Also identify the type of wave. Amplitude wavelength trough Transverse rest position crest Use the terms at the bottom of the chart to complete the concept map. longitudinal transverse amplitude wavelength frequency absorption diffraction refraction reflection transmission
