Figure

Figure 1: Comparison between the Rusanov scheme (100 cells, CFL=0.4) and the exact solution at time t = 1.
Figure 2 depicts the error with respect to the space step. We can easily see that the rate of convergence is 1, that is to say that the constraint does not affect the accuracy of the numerical scheme.
Figure 4: Variation of average quantities with respect to the time lag ϕ, com- com-pared to the ideal case (one light).
