SUMMARY
The discussion focuses on calculating the oscillation amplitude of a vibrating string at various points, specifically for a string of length 2.0 m vibrating at its second harmonic frequency with a maximum amplitude of 2.0 cm. The amplitude at any point x is determined using the equation A(x) = 2a sin(kx), where k is calculated as k = 2π/wavelength. Participants emphasized the importance of using consistent units, converting centimeters to meters, and correctly interpreting the amplitude in relation to the harmonic frequency.
