(B) The concept of secondary wavelets for the propagation of a wave was proposed by Christiaan Huygens in his wave theory of light. According to Huygens' principle,every point on a primary wavefront acts as a source of secondary spherical wavelets,which spread out in all directions with the speed of light in the medium. The new wavefront at a later time is the forward envelope of these secondary wavelets. Therefore,the correct option is $B$.
