WebNov 30, 2024 · Huygen's proposed that light is a longitudinal wave in the aether medium - a medium that pervades the entire universe. The set of particles oscillating in phase with each other is called a wavefront. Point sources give out spherical wavefronts, while sources at infinity give plane wavefronts. Created by Mahesh Shenoy.WebWhat is the shape of the wavefront in each of the following cases: (a) Light diverging from a point source.(b) Light emerging out of a convex lens when a point source is placed at its focus.(c) The portion of the wavefront of light from a distant star intercepted by the Earth.edf uk office
