When sound wave is refracted from air to water, which of the following will remain unchanged?
- A. wave number
- B. wavelength
- C. wave velocity
- D. frequency
Step-by-step solution
When a sound wave passes from air to water, the frequency is determined by the source and remains constant. The wave velocity changes because sound travels faster in water, and since v = fλ, the wavelength and wave number (inversely related to wavelength) change accordingly.
