The discussion centers on calculating the phase difference in a traveling harmonic wave with a frequency of 10 Hz and a speed of 200 m/s. The phase difference can be determined using the formula Δφ = (2π/λ) * Δx, where λ is the wavelength and Δx is the distance between the two positions. Given the wave speed and frequency, the wavelength can be calculated as λ = v/f = 200 m/s / 10 Hz = 20 m. Thus, for two positions 3 m apart, the phase difference is Δφ = (2π/20 m) * 3 m = 0.3π radians.
