Answer

Explanation:

Step1: Recall the speed formula

Speed is defined as the distance traveled divided by the time taken. For a wave, the general formula for speed (v) is (v=\frac{d}{t}), where (d) is the distance traveled and (t) is the time.

Step2: Analyze each option

  • Option 1: Distance traveled / amplitude. Amplitude is the maximum displacement of a wave from its equilibrium position and has no relation to speed.
  • Option 2: Number of wavelengths / amplitude. Again, amplitude is not relevant to speed calculation.
  • Option 3: Number of wavelengths / time. This is related to frequency ((f=\frac{n}{t}), where (n) is the number of wavelengths), not speed.
  • Option 4: Distance traveled / time. This is the correct formula for speed.

Answer:

distance traveled / time
