WebbSpherical waves are generally seen as sound waves and light waves. They have a point source and the waves formed, move forward in all directions. A plane wave moves forward in only one direction. A true plane wave ceases to exist in reality. This is because then it would require filling the entire space, which is not seen in experiments. Webb17 mars 2016 · HUYGEN’S THEORY OF DOUBLE REFRACTION • According to Huygen’s theory , a point in a doubly refracting or birefringent crystal produces 2 types of wavefronts: The wavefront corresponding to the O-ray Spherical wavefront oThe ordinary wave travels with same velocity in all directions and so the corresponding wavefront is spherical.
