6.1.2 Properties of Waves

• What are the key properties of waves?

  Wavelength, frequency, period, amplitude, wave speed
• The wavelength of a wave is inversely related to its frequency
• What is the formula for frequency in terms of period?

  $f =$$\frac{1}{T}$
• The amplitude of a wave is related to its energy
• Wave speed can be calculated as the distance traveled over time.
• What is the definition of wavelength?

  Distance between crests
• Match the wave property with its formula:

  Wave Speed ↔️ $v =$$fλ$

  Frequency ↔️ $f =$$\frac{1}{T}$

  Period ↔️ $T =$$\frac{1}{f}$
• What unit is amplitude measured in?

  Meters
• Higher amplitude waves carry more energy.
• Amplitude is measured in meters
• What is the symbol for wavelength?

  $λ$
• Wavelength is inversely proportional to frequency.
• What unit is frequency measured in?

  Hertz
• The period of a wave is the time taken for one complete wave
• Frequency and period are inversely related.
• What is the relationship between frequency and period?

  f = \frac{1}{T}</latex>
• The wavelength of a wave is inversely related to its frequency
• What property of a wave is related to its energy?

  Amplitude
• The number of waves passing a point per second is called frequency.
• Higher amplitude waves carry more energy
• What does amplitude measure?

  Maximum displacement
• Wavelength is directly related to wave speed.
• The formula relating wavelength, wave speed, and frequency is $λ =$$\frac{v}{f}$
• What is the unit for frequency?

  Hertz
• What is the formula for wavelength in terms of wave speed and frequency?

  $λ =$$\frac{v}{f}$
• Frequency is measured in Hertz
• What is the formula for frequency in terms of period?

  f = \frac{1}{T}</latex>
• The formula for wave speed is v = fλ
• What is the direction of displacement in a transverse wave relative to the direction of propagation?

  Perpendicular
• Sound waves are examples of longitudinal waves.
