We have found several cases in our numerical simulations where Richtmyer's prescription fails to give the correct growth rate for the Richtmyer-Meshkov instability in the linear regime. Another expression, due to Fraley [Phys. Fluids 29, 376 (1986)], agrees with our simulations. We discuss recent experiments and report two new types of perturbation freeze-out, single-shock and double-interface, which are quite distinct from the previously reported double-shock freeze-out.
