Longitudinal and Transverse Waves

• What are the basics of waves discussed in the video?

  Labeling parts, calculating wave speed, types
• What do waves transfer from one place to another?

  Energy
• What do waves not transfer?

  Any matter
• How does our brain interpret wave energy?

  By building images and tunes
• What is the distance in a displacement-distance graph?

  How far the wave has traveled
• What does displacement represent in a displacement-distance graph?

  How far from the equilibrium point
• What is the maximum displacement of a wave called?

  Amplitude
• What is the opposite of the crest in a wave?

  Trough
• What is the distance of one entire oscillation called?

  Wavelength
• What does a displacement-time graph show?

  Displacement over time
• What is the time period of a wave?

  Time for one complete oscillation
• How do you calculate frequency from the time period?

  Frequency = 1 / time period
• If the time period is 0.5 seconds, what is the frequency?

  2 Hz
• If the frequency is 4 Hz, what is the time period?

  0.25 seconds
• How do you calculate wave speed?

  Wave speed = wavelength × frequency
• What is the wave speed of a sound wave with a frequency of 400 Hz and wavelength of 70 cm?

  280 m/s
• What is the first step in calculating wave speed?

  Convert wavelength to meters
• What are transverse waves?

  Oscillations are perpendicular to energy transfer
• What are examples of transverse waves?

  Light waves, water waves, guitar strings
• What are longitudinal waves?

  Oscillations are parallel to energy transfer
• What are examples of longitudinal waves?

  Sound waves, seismic P waves
• What are the key differences between transverse and longitudinal waves?

  • Transverse waves: oscillations perpendicular to energy transfer
  • Longitudinal waves: oscillations parallel to energy transfer
  • Examples: Light waves (transverse), Sound waves (longitudinal)
• What is the relationship between wavelength, frequency, and wave speed?

  • Wave speed = wavelength × frequency
  • Wavelength: distance of one oscillation
  • Frequency: number of oscillations per second
• What is the significance of amplitude and wavelength in wave behavior?

  • Amplitude: maximum displacement from equilibrium
  • Wavelength: distance for one complete oscillation
  • Both affect wave energy and characteristics
