  • What is the distance between one wave and the next called?
    The distance between one wave and the next is called the wavelength.
  • What is the distance between two crests of a wave?
    The distance between two crests of a wave is the wavelength.
  • What is a medium in the context of waves?
    A medium is the material or substance through which a wave travels.
  • Which type of wave has the longest wavelength?
    Among waves, those with the lowest frequency have the longest wavelength, according to the relationship λ = v/f.
  • What is the frequency of a wave?
    The frequency of a wave is the number of cycles that occur per unit time.
  • What is the relationship between wavelength and frequency?
    Wavelength and frequency are inversely related: as frequency increases, wavelength decreases, given a constant wave speed (v = λf).
  • What type of wave are water waves?
    Water waves are primarily transverse waves.
  • What is the best description of a wave?
    A wave is a moving disturbance or oscillation that carries energy through a medium or space.
  • If the frequency of a wave doubles, what happens to its wavelength (assuming constant speed)?
    If frequency doubles and speed remains constant, the wavelength is halved.
  • What is the crest of a wave?
    The crest of a wave is the highest point of the wave.
  • How do you find the period of a wave?
    The period of a wave is found by taking the reciprocal of the frequency: T = 1/f.
  • How do you measure a wavelength?
    Wavelength is measured as the distance between two consecutive points in phase, such as crest to crest or trough to trough.
  • What is the highest point of a wave called?
    The highest point of a wave is called the crest.
  • What is the source of all wave motion?
    The source of all wave motion is an oscillation or vibration.
  • A wave is a pattern of motion that transports what?
    A wave is a pattern of motion that transports energy.
  • How does amplitude affect wavelength?
    Amplitude does not affect wavelength; amplitude is the maximum displacement, while wavelength depends on frequency and speed.
  • What is the highest point of a transverse wave called?
    The highest point of a transverse wave is called the crest.
  • What does a wave carry?
    A wave carries energy.
  • Can a mechanical wave travel through a vacuum?
    No, a mechanical wave cannot travel through a vacuum; it requires a medium.
  • When amplitude increases, what happens to wavelength?
    When amplitude increases, wavelength does not change; amplitude and wavelength are independent properties.
  • What kind of wave is an ocean wave?
    An ocean wave is primarily a transverse wave.
  • What does a wave transfer?
    A wave transfers energy.
  • What is the distance between adjacent compressions in a longitudinal wave?
    The distance between adjacent compressions in a longitudinal wave is the wavelength.
  • What happens to the wavelength when the frequency increases (assuming constant speed)?
    When frequency increases and speed is constant, the wavelength decreases.
  • What is frequency a measure of?
    Frequency is a measure of how many cycles occur per unit time.
  • What is the measurement of a wave's height?
    The measurement of a wave's height is called amplitude.
  • What does frequency describe in a wave?
    Frequency describes how often cycles of the wave occur per unit time.
  • As frequency increases, what happens to the wavelength (assuming constant speed)?
    As frequency increases, wavelength decreases if speed is constant.
  • What is frequency measured in?
    Frequency is measured in hertz (Hz), which is cycles per second.
  • What defines the amplitude of a wave?
    Amplitude is defined as the maximum displacement from the equilibrium position.
  • Which statement best describes wavelength?
    Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest.
  • What is matter through which a wave travels called?
    Matter through which a wave travels is called a medium.
  • How are frequency and wave period related?
    Frequency and period are inversely related: f = 1/T and T = 1/f.
  • How does changing the frequency affect the wavelength (assuming constant speed)?
    Increasing frequency decreases wavelength, and decreasing frequency increases wavelength, if speed is constant.
  • How often a wave occurs is the wave’s what?
    How often a wave occurs is the wave’s frequency.
  • How does changing amplitude affect wavelength?
    Changing amplitude does not affect wavelength; they are independent properties.
  • How does wavelength change as frequency increases (at constant speed)?
    As frequency increases, wavelength decreases if speed is constant.
  • How far does a wave travel in one period?
    A wave travels one wavelength in one period.
  • What is a wave?
    A wave is a moving disturbance or oscillation that carries energy through a medium or space.
  • What is a mechanical wave?
    A mechanical wave is a wave that requires a medium to travel through.
