Two sound waves are emitted from identical sources at the same time. They each travel a distance of 10 m, but one wave reaches t
kompoz [17]

Answer:

<em>Varying frequency</em> between both waves accounts for difference in speed.

Explanation:

The speed of a wave is dependent on four major factors:

  1. wavelength
  2. frequency
  3. medium, and
  4. temperature 

Assuming equal temperature and medium of travel of these sound waves, and given that the wavelength (that is distance of travel) is equal, the only varying factor would be their frequency.

Wave speed is calculated by multiplying the wavelength times the frequency

⇒ Speed = λ * <em>f</em>
