Which of the following quantities remains unchanged when a sound wave travels from one medium to another?
A. Velocity
B. Wavelength
C. Frequency✓ Correct Answer
D. Amplitude
💡 Solution & Explanation
The frequency of a wave is determined entirely by the source and remains constant when the wave transitions into a new medium. Wave velocity and wavelength change depending on the optical or acoustic density of the media encountered during propagation. General science queries frequently assess wave properties and the constancy of frequency across boundaries.
