Wave Equations

• What is the formula for the period of a wave?

  Period = 1 ÷ frequency
• What is the formula for wave speed?

  Wave speed = frequency × wavelength
• What is the relationship between period and frequency?

  Period = 1 ÷ frequency
• What is the unit of frequency?

  Hertz (Hz)
• What is the unit of wave speed?

  Meters per second (m/s)
• What is the unit of wavelength?

  Meters (m)
• How is wave speed calculated?

  By multiplying frequency and wavelength
• What does frequency measure in waves?

  The number of waves passing a point per second
• What does wavelength represent?

  The distance between two consecutive wave peaks
• How does changing the frequency affect the period of a wave?

  Increasing frequency decreases the period
• How do wave speed and wavelength relate to frequency?

  Wave speed equals frequency times wavelength
• If a wave has a frequency of $2 \text{ Hz}$, what is its period?


  $0.5 \text{ s}$
• If a wave travels at $300 \text{ m/s}$ and has a wavelength of $3 \text{ m}$, what is its frequency?


  $100 \text{ Hz}$
• If the frequency of a wave is $5 \text{ Hz}$, what is its wavelength if the wave speed is $20 \text{ m/s}$?


  $4 \text{ m}$
