4-2 Chapter 11 Assessment

Match the following concepts with its definition. Wave transports energy from one place to another without physically transporting any material. Source the object that creates the energy to create a wave. Receiver the object that receives the energy in the form of a wave. Disturbance oscillation that changes the state of a medium through which any wave is being propagated. Medium is any substance or object that carries a wave. Waves that need a material medium to propagate. Electromagnetic waves Mechanical waves Longitudinal waves Transverse waves Waves that can travel without needing a material medium to propagate. Electromagnetic waves Mechanical waves Longitudinal waves Transverse waves Are waves in which motion of material is perpendicular to the direction of wave propagation. Electromagnetic waves Mechanical waves Longitudinal waves Transverse waves Waves that move in the same direction as the displacement of the medium. Electromagnetic waves Mechanical waves Longitudinal waves Transverse waves Read the types of waves and classify them as Electromagnetic waves or Mechanical waves. Electromagnetic Waves x-Rays Light Radio TV signals Mechanical Waves Sea Sound Seismic tsunami The number 1 represents Amplitude Crests Troughs Wavelength The number 2 represents Amplitude Crests Troughs Wavelength The number 3 represents Amplitude Crests Troughs Wavelength The number 4 represents Amplitude Crests Troughs Wavelength Are the parts in a transverse wave that rises. Amplitude Crests Troughs Wavelength Are the parts in a transverse wave that descends. Amplitude Crests Troughs Wavelength Is the distance from the string’s horizontal position to the highest point of the crest or the lower point of the trough. Amplitude Crests Troughs Wavelength Is the distance between two consecutive crests or troughs. Amplitude Crests Troughs Wavelength It is represented by the Greek symbol lambda (λ). Amplitude Crests Troughs Wavelength Is a rapid back-and-forward motions of the particles the material is made of. Longitudinal Sounds Transverse Vibrations Is a longitudinal wave that moves through the air or any material medium that we can hear. Longitudinal Sounds Transverse Vibrations Is an instrument used to represent sound waves in a visual way. Wavemeter Oscillometer Soundmeter Graphmeter
