Both the s and p waves will travel with the same speed. One can show the wave front by drawing a circile of radius c/no with the center at the interface at point O, where the radiation is hitting the interface as shown in fig. The wave front will be spherical corresponding to both the components, . The situation will be similar to that of isotropic medium.
