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:
- wavelength
- frequency
- medium, and
- 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>
Answer:
No.
Explanation:
