allison wants to calculate the speed of a sound wave. which formula should she use? o distance traveled / amplitude o number of wavelengths / amplitude o number of wavelengths / time o distance traveled / time

Answer

Explanation:

Step1: Recall speed - definition

Speed is defined as the distance traveled per unit time for any object in motion. Sound waves are no exception.

Step2: Analyze options

  • "distance traveled / amplitude": Amplitude is the maximum displacement of a wave from its equilibrium position and has nothing to do with speed calculation.
  • "number of wavelengths / amplitude": Amplitude is not related to the calculation of speed in this context.
  • "number of wavelengths / time": This is related to frequency (number of wavelengths per unit time), not speed.
  • "distance traveled / time": This is the correct formula for speed, which applies to sound - wave speed calculation.

Answer:

distance traveled / time
