We compute the asymptotic expectation of the number of open nodal lines for random waves on smooth planar domains. We find that for both the long energy window [0, λ], and the short one [λ, λ +1], the expected number of open nodal lines is proportional to λ, asymptotically as λ → ∞. Our results are consistent with the predictions of Blum, Gnutzmann, and Smilansky [4] in the physics literature.
