Waves - Longitudinal & Transverse

• What are the two main types of waves discussed in the video?

  Transverse and longitudinal waves
• What is the primary function of waves as described in the video?

  Waves transfer energy from one place to another without transferring matter
• How does our brain interpret the energy transferred by waves?

  Our brain builds images and tunes from the light and sounds it receives
• What do the terms 'displacement' and 'distance' refer to in the context of waves?

  Distance refers to how far the wave has traveled, while displacement refers to how far the wave has oscillated from the equilibrium point
• What is the maximum displacement of a wave called?

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

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

  Trough
• How does a displacement-time graph differ from a displacement-distance graph?

  A displacement-time graph has time on the x-axis instead of distance
• What does the time period of a wave represent?

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

  The frequency is 2 hertz
• How do you calculate the frequency of a wave using the time period?

  Frequency equals 1 divided by the time period
• If a wave has a frequency of 4 hertz, what is its time period?

  The time period is 0.25 seconds
• How is wave speed calculated?

  Wave speed is calculated by multiplying the wavelength by the frequency
• What is the wave speed of a sound wave with a frequency of 400 hertz and a wavelength of 70 centimeters?

  The wave speed is 280 meters per second
• What is the relationship between the oscillations in transverse waves and the direction of energy transfer?

  In transverse waves, oscillations are perpendicular to the direction of energy transfer
• What are some examples of transverse waves?

  Examples include electromagnetic waves, ripples in water, and waves on guitar strings
• How do oscillations in longitudinal waves differ from those in transverse waves?

  In longitudinal waves, oscillations are parallel to the direction of energy transfer
• What happens in longitudinal waves that leads to regions of compression and rarefaction?

  Longitudinal waves create regions that are more spread out and others that are more compressed
• What are some examples of longitudinal waves?

  Examples include 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 waves: electromagnetic waves, water waves
  • Examples of longitudinal waves: sound waves, seismic p waves
