Transmission of a Wave z Assume a light string is attached to a heavier string z The pulse travels through the light string and reaches the boundary z The part of the pulse that is reflected is inverted z The reflected pulse has a smaller amplitude animation

Transmission of a Wave z Conservation of energy governs the pulse z When a pulse is broken up into reflected and transmitted parts at a boundary, the sum of the energies of the two pulses must equal the energy of the original pulse
