Evaporation can decrease the amount of water. Dust from the surroundings can enter the water. The water can freeze if the surrounding temperature decreases sufficiently.
The wavelength of a sound wave moving at 340 m/s and with a frequency of 256 Hz is calculated using the the below formula
wavelength = speed of the wave/frequency
speed of the wave = 340 m/s
frequency = 256 Hz
wavelength is therefore = 340/256 = 1.32 m
