Question

What is the frequency of a wave with a wavelength of \( 2 \, \text{m} \) and a velocity of \( 4 \, \text{m/s} \)?

• A. \( 2 \, \text{Hz} \)
• B. \( 0.5 \, \text{Hz} \)
• C. \( 1 \, \text{Hz} \)
• D. \( 4 \, \text{Hz} \)

Hint:

Always remember the formula: \( v = f \lambda \) for waves. If you know any two quantities (velocity, frequency, wavelength), you can solve for the third.
