Question

Quizplus · Accepted Answer

The speed of a sound wave in air primarily depends on the air temperature. Changes in temperature can affect the speed of sound because sound travels faster in warmer air and slower in colder air. Wavelength and frequency do not directly affect the speed of sound; instead, they are related to the speed of sound through the wave equation (speed = frequency × wavelength), where the speed of sound is the factor that influences the relationship between frequency and wavelength.
