Answer:
"The speed of sound can change when sound travels from one medium to another. However, the frequency usually remains the same because it is like a driven oscillation and maintains the frequency of the original source. If v changes and f remains the same, then the wavelength λ must change. "

Answer:
No
Explanation:
The answer to this question is clearly no. You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels (dB).
