4.1 Properties of Waves

• What is the definition of a disturbance in the context of waves?

  Disrupts medium equilibrium
• What is the highest point of a wave called?

  Crest
• What is the distance between two consecutive crests of a wave called?

  Wavelength
• What is the lowest point of a wave called?

  Trough
• What is the unit of measurement for wavelength?

  Meters
• The wavelength is the distance between two consecutive crests or troughs
• What is the lowest point of a wave called?

  Trough
• What is the amplitude of a wave?

  Maximum displacement from rest
• The highest point of a wave is called the crest
• What is the trough of a wave?

  Lowest point of the wave
• Match the wave part with its definition:

  Crest ↔️ Highest point of the wave

  Trough ↔️ Lowest point of the wave

  Amplitude ↔️ Maximum displacement from rest

  Wavelength ↔️ Distance between crests
• The maximum displacement of a wave from its resting position is called the amplitude
• Match the wave part with its definition:

  Crest ↔️ Highest point of the wave

  Trough ↔️ Lowest point of the wave

  Amplitude ↔️ Maximum displacement from rest

  Wavelength ↔️ Distance between crests
• The lowest point of a wave is called the trough
• The maximum displacement of a wave from its resting position is called the amplitude
• Wavelength is the distance between two consecutive crests or troughs.


  True
• What is the amplitude of a wave defined as?

  Maximum displacement from rest
• What is the lowest point of a wave called?

  Trough
• Arrange the following wave parts in a logical order from highest to lowest point:

  1️⃣ Crest

  2️⃣ Resting position

  3️⃣ Trough
• What is the wavelength of a wave defined as?

  Distance between crests
• Wavelength is the distance between two consecutive crests or troughs.


  True
• The highest point of a wave is called the crest
• Match the wave part with its definition:

  Wavelength ↔️ Distance between crests

  Crest ↔️ Highest point of wave

  Trough ↔️ Lowest point of wave

  Amplitude ↔️ Max displacement from resting position
• What is the trough of a wave?

  Lowest point of wave
• Match the wave part with its diagram representation:

  Crest ↔️ Highest point

  Trough ↔️ Lowest point

  Amplitude ↔️ Vertical distance from resting position

  Wavelength ↔️ Horizontal distance between crests
• Waves transfer energy without moving the medium itself.


  True
• What is the lowest point of a wave called?

  Trough
• The amplitude of a wave is measured from the crest to the trough.

  False
• Amplitude measures the maximum displacement of a wave from its resting position.


  True
• Match the wave part with its definition:

  Crest ↔️ The highest point of the wave

  Trough ↔️ The lowest point of the wave

  Amplitude ↔️ Maximum displacement from rest

  Wavelength ↔️ Distance between crests
• The crest of a wave is its highest point.


  True
• The maximum displacement of a wave from its resting position is its amplitude
• The wavelength is the distance between two consecutive crests or troughs.


  True
• What is the wavelength of a wave?

  Distance between two crests
• The amplitude is the maximum displacement of the wave from its resting position
• What is the crest of a wave?

  Highest point of the wave
• The highest point of a wave is called the crest
• The highest point of a wave is called the crest
• What is the crest of a wave?

  Highest point of the wave
• What is the highest point of a wave called?

  Crest
