Formulas and Key Relations

1. Bounded Medium and Reflection

Incident progressive wave: y = a sin[(2π/λ)(vt - x)]

Reflected wave from rigid/closed boundary: y = -a sin[(2π/λ)(vt + x)]

2. Nodes, Antinodes, and Properties

Stationary wave from rigid boundary: y = -2a sin[(2πx)/λ] cos[(2πt)/T]

Stationary wave from free boundary: y = 2a cos[(2πx)/λ] sin[(2πt)/T]

3. Closed Organ Pipe

Closed pipe allowed wavelengths: λ = 4l/(2m - 1)

Closed pipe mth mode frequency: n_m = [(2m - 1)v]/(4l)

Closed pipe fundamental frequency: n_1 = v/(4l)

Closed pipe with end correction: n_1 = v/[4(l + 0.6r)]

4. Open Organ Pipe

Open pipe allowed wavelengths: λ = 2l/m

Open pipe mth mode frequency: n_m = mv/(2l)

Open pipe fundamental frequency: n_1 = v/(2l)

Open pipe with end correction: n_1 = v/[2(l + 1.2r)]
