Questions & Step-by-Step Solutions

What is the relationship between the frequency and wavelength of a wave?
Correct Answer: Speed = Frequency × Wavelength
  • Step 1: Understand that waves travel through space and have two important characteristics: frequency and wavelength.
  • Step 2: Frequency is how many waves pass a point in one second, measured in Hertz (Hz).
  • Step 3: Wavelength is the distance between two consecutive points of the wave, like from one peak to the next peak.
  • Step 4: The speed of a wave is how fast it travels, and it can be calculated using the formula: Speed = Frequency × Wavelength.
  • Step 5: If you know the speed of the wave, you can find the frequency if you know the wavelength, or vice versa.
  • Step 6: Rearranging the formula gives you: Frequency = Speed / Wavelength and Wavelength = Speed / Frequency.
