A pressure gauge is sensitive to pressure variations that are close to ±1 cm or above. Calculate minimum wavelength at which a wave of 10 cm amplitude will be detectable in 1000 m of water.
Note, the pressure does not register smaller pressure variations

As a certain sound wave travels through the air, it produces pressure variations (above and below atmospheric pressure) given by ΔP = 1.18 sin(πx - 332πt) in SI units. (Note: Use the following values as needed, unless otherwise specified. The equilibrium density of air is ρ = 1.20 kg/m3. Pressure variations ΔP are measured relative to atmospheric pressure, 1.013 105 Pa.) (a) Find the amplitude of the pressure variations. Pa (b) Find the frequency of the sound wave. Hz (c)...
