Questions and Answers

What does the amplitude of a wave measure?

  • The distance between two repeating waves
  • The height of a wave from the center line to the crest or trough (correct)
  • The speed at which a wave moves through a medium
  • The time it takes for a wave to travel a distance

Which statement best describes the wavelength of a wave?

  • It is the vertical distance from the crest to the trough.
  • It represents the energy carried by the wave.
  • It measures the strength of the wave as it travels.
  • It is the horizontal distance between two repeating peaks. (correct)

How does a medium (the material, ie, liquid or gas)affect wave behavior?

  • It can influence both the speed and the energy of the wave. (correct)
  • It changes the wavelength but not the energy transfer.
  • It determines the speed of the wave but not the amplitude.
  • It has no effect on the wave's movement.

Study Notes

  • Waves originate from vibrations at a source, causing disturbances that spread outward.
  • Waves exhibit repeating patterns, defining their shape and length.
  • These characteristics aid in wave classification and describing their behavior.
  • Wave behavior is affected by the medium they traverse.
  • Understanding individual wave characteristics is crucial.
  • The definition of a wave is a disturbance that transfers energy from one place to another.
  • Waves transfer energy through mediums.
  • A wave's amplitude directly correlates to the energy it carries.

Wavelength

  • Wavelength is the distance between two successive peaks or troughs of a wave.
  • Measured horizontally.

Amplitude

  • Amplitude is the height from the center line to a peak (crest) or trough.
  • A measure of the wave's energy content.
  • Higher amplitude equates to more energy carried by the wave.
  • Crest is the highest point of a wave.
  • Trough is the lowest point of a wave.

Wave Medium

  • A wave's medium (solid, liquid, or gas) influences its path.
  • The medium carries the wave's energy.
