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

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
