  • What is the highest point of a wave?
    The highest point of a wave is called the crest.
  • What type of wave is an ocean wave?
    An ocean wave is primarily a transverse wave.
  • Through which can a mechanical wave travel?
    A mechanical wave can travel through solids, liquids, or gases, but not through a vacuum.
  • What is the amplitude of a wave?
    Amplitude is the maximum displacement from the equilibrium position.
  • What is the period of a wave?
    The period is the time it takes for one complete cycle of the wave.
  • What is the formula relating wave speed, wavelength, and frequency?
    Wave speed equals wavelength times frequency: v = λf.
  • What is a transverse wave?
    A transverse wave is a wave in which the oscillation is perpendicular to the direction of propagation.
  • What is a longitudinal wave?
    A longitudinal wave is a wave in which the oscillation is parallel to the direction of propagation.
  • What is the trough of a wave?
    The trough is the lowest point of a wave.
  • What is the unit of frequency?
    The unit of frequency is hertz (Hz).
  • What is the unit of wavelength in the SI system?
    The unit of wavelength in the SI system is the meter (m).
  • What is the unit of period?
    The unit of period is the second (s).
  • What is the main difference between transverse and longitudinal waves?
    In transverse waves, oscillation is perpendicular to propagation; in longitudinal waves, oscillation is parallel to propagation.
  • Can longitudinal waves propagate in fluids?
    Yes, longitudinal waves can propagate in fluids.
  • Can transverse waves propagate in fluids?
    Transverse waves do not propagate well in fluids.
  • What is the rarefaction in a longitudinal wave?
    Rarefaction is the region where particles are spread apart in a longitudinal wave.
  • What is compression in a longitudinal wave?
    Compression is the region where particles are close together in a longitudinal wave.
  • What is the equilibrium position in a wave?
    The equilibrium position is the central position where the medium would be if there were no wave.
