SUMMARY
The discussion focuses on calculating the number of sound wavelengths in air compared to water at a temperature of 10°C, using the speed of sound in water (5220 km/h) and a frequency of 500 Hz. The wavelength in water is determined using the formula λ = v/f, where v is the speed of sound and f is the frequency. To find the wavelength in air, the speed of sound in air at 10°C (approximately 340 m/s) must be used. The final conclusion is that the number of wavelengths in air is significantly greater than in water due to the difference in speed of sound.
