Question

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

Explanation:

Step1: Recall speed formula

Speed is defined as the distance traveled per unit - time for any object or wave.

Step2: Apply to sound wave

The speed of a sound wave is also given by the distance it travels divided by the time taken. The other options involving amplitude are incorrect as amplitude is related to the intensity of the wave and not its speed, and number of wavelengths/time gives the frequency.

Answer:

distance traveled / time
