transverse and longitudinal waves

• What are the two types of waves?

  Transverse and longitudinal waves
• How are the vibrations in transverse waves oriented?

  Perpendicular to the direction of energy transfer
• What type of wave is produced when a spring is wiggled from side to side?

  Transverse wave
• How are the vibrations in longitudinal waves oriented?

  Parallel to the direction of energy transfer
• What happens when you push the end of a spring?

  You create a longitudinal wave
• What is the formula for wave speed?

  Wave speed = Frequency × Wavelength
• What does wave speed represent?

  The speed at which energy is transferred
• If a radio wave has a frequency of $12.0 \times 10^6 \text{ Hz}$, what is its wavelength if the speed is $3.0 \times 10^8 \text{ m/s}$?


  $25 \text{ m}$
• What is the key difference between longitudinal and transverse waves?

  Direction of oscillation vs. energy transfer
• What is the unit for frequency?

  Hertz (Hz)
• What is the unit for wavelength?

  Meter (m)
• What is the unit for wave speed?

  Meter per second (m/s)
