We further use this result to show that the optimal $(L^p, L^2)$ restriction theorem implies the sharp isotropic decay rate for the Fourier transform of the Lebesgue measure carried by compact convex finite hypersurfaces.Classical Analysis and ODEsFourier transform, $L^2$ restriction theorem, and scalingtext
