If the wavelength of a 4.65 ✕ 102 Hz sound in freshwater is 3.45 m, what is the speed of sound in fresh water?

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

1604m/s

Explanation:

Speed (v) of a sound is expressed as a function of its wavelength(¶) and frequency (f). It is expressed as the product of the frequency of the sound and its wavelength. Mathematically,

Speed = frequency × wavelength

v = f¶

Given frequency = 4.65×10²Hz

¶ = 3.45m

v = 4.65×10²×3.45

v = 1604m/s

Therefore the wavelength of the sound in fresh water is 1604m/s

im sorry i dont know
