1.3.1 Properties of Waves

• What is a wave defined as in physics?

  A disturbance transporting energy
• What unit is used to measure frequency?

  Hertz (Hz)
• Water waves are examples of transverse
• Wavelength and frequency are inversely proportional to each other.
• Match the wave property with its description:

  Wave Speed ↔️ Speed at which the wave travels

  Frequency ↔️ Number of cycles per unit time
• One Hertz (Hz) equals one cycle per second
• What is the unit of wave speed?

  Meters per second (m/s)
• Amplitude is measured in meters or degrees
• What is the distance between two consecutive peaks of a wave called?

  Wavelength
• Sound waves are an example of longitudinal waves.
• A sound wave with a frequency of 440 Hz and a wavelength of 0.75 m has a wave speed of 330 m/s.
• Waves can be classified as transverse or longitudinal
• Match the wave type with its vibration direction:

  Transverse Waves ↔️ Perpendicular to direction of travel

  Longitudinal Waves ↔️ Parallel to direction of travel
• Arrange the following wave properties in order from largest to smallest:

  1️⃣ Wavelength

  2️⃣ Frequency

  3️⃣ Amplitude
• What is frequency measured in?

  Hertz (Hz)
• What does amplitude represent in a wave?

  Wave intensity
• What does frequency describe?

  Wave cycles per unit time
• Higher frequency waves have shorter wavelengths if wave speed is constant.
• What does a wave transport through a medium?

  Energy
• Match the type of wave with its vibration direction:

  Transverse waves ↔️ Perpendicular

  Longitudinal waves ↔️ Parallel
• Wavelength and frequency are inversely proportional to each other.
• Wavelength is the distance between two consecutive peaks of a wave.
• In transverse waves, vibrations are parallel to the direction of wave travel.

  False
• What is the unit of measurement for wavelength?

  Meters (m)
• 1 Hz is equal to one wave cycle per second
• What is frequency measured in?

  Hertz (Hz)
• Wavelength is the distance between two identical points on a wave
• What does the amplitude of a wave represent?

  Maximum displacement
• The maximum displacement of a wave from its resting position is its amplitude
• In which type of wave do vibrations occur parallel to the direction of travel?

  Longitudinal waves
• What is the formula relating wave speed, frequency, and wavelength?

  $v =$$f \lambda$
