Abstract
We derive a nonlinear supersymmetric a model for the transport of ligh t (classical waves) through a disordered medium. We compare this model with the well-established nonlinear a model for the transport of elec trons (Schrodinger waves) and display similarities of and differences between both cases. We show that for weak disorder both models are equ ivalent (have the same effective Lagrangian). This effective Lagrangia n correctly reproduces the (different) Ward identities for Schrodinger waves and for classical waves.
