Answer:
- 1,480 m/s
- 296 m/s
Explanation:
Speed of sound in water = Frequency * Wavelength
= 592 * 2.5
= 1,480 m/s
If the wavelength is increased to 5m, the frequency would reduce because higher wavelengths have lower frequencies.
Frequency (from above formula) = Speed of sound in water/ Wavelength
= 1,480/5
= 296 m/s.
