SUMMARY
The pressure amplitude of a sound wave with an intensity level of 65 dB can be calculated using the formula: Pressure = Intensity / Velocity of Sound. The intensity (I) is derived from the reference intensity level (I_0) using the equation I = I_0 * 10^(dB/10), where I_0 is 10^-12 W/m². The velocity of sound (V_SOUND) is approximately 340 m/s. The user attempted to calculate the pressure amplitude but encountered discrepancies with the answer key, indicating a potential miscalculation in the intensity or application of the formulas.
