longitudinal/ transverse

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

  Labeling parts, calculating wave speed, and differences between transverse and longitudinal waves
• What do waves transfer from one place to another?

  Energy
• What happens when light waves pass from a phone screen to your eye?

  Only energy is being transferred
• How does our brain interpret the energy received from waves?

  It builds up images and tunes
• What is the term for how far the wave has traveled from the starting point?

  Distance
• What is the maximum displacement of a wave called?

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

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

  Trough
• What does a displacement time graph show on the x-axis?

  Time
• What is the time period of a wave?

  The time it takes for one complete oscillation
• If the time period of a wave is 0.5 seconds, what is its frequency?

  2 Hz
• How do you calculate frequency from the time period?

  Frequency = 1 / Time period
• If the frequency of a wave is 4 Hz, what is its 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 a wavelength of 70 cm?

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

  Convert the wavelength to meters
• What are the oscillations in transverse waves relative to the direction of energy transfer?

  Perpendicular
• What types of waves are typically transverse?

  Electromagnetic waves, ripples in water, and waves on strings
• How do oscillations in longitudinal waves differ from those in transverse waves?

  They are parallel to the direction of energy transfer
• What are examples of longitudinal waves?

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

  • Transverse waves: Oscillations are perpendicular to energy transfer
  • Longitudinal waves: Oscillations are parallel to energy transfer
  • Examples of transverse: Light waves, water waves
  • Examples of longitudinal: Sound waves, seismic P-waves
• What are the key equations related to wave properties?

  1. Frequency = 1 / Time period
  2. Wave speed = Wavelength × Frequency
  3. Time period = 1 / Frequency
