Answer:
Explanation:
Given that, the wavelength is 3.45m
λ=3.45m
Frequency is 4.65×10^2Hz
F=4.65×10^2Hz
Speed is given as
V=Fλ
Then,
V=4.65×10^2× 3.45
V=1604.25m/s
The speed of sound in fresh water is 1604.25m/s
A. Air, desk, water. sound travels the slowest through air and the fastest through liquids. solids are somewhere in the middle.
