Practice question

**Transverse wave velocity** depends on medium not frequency alone. For string under tension, v ∝ √(T/μ), calculation requires μ from mass and length, then square root evaluation, giving v in m/s, then f = v/λ for given wavelength. Energy dissipation occurs due to absorption and scattering in the medium, reducing intensity as the wave spreads and loses energy to internal friction or obstacles. Using v = fλ and standing-wave condition fₙ = n v/(2L) or v/(4L) as applicable, calculation yields Energy dissipation, illustrating frequency-length-speed interdependence and quantization by boundaries.
