Momentum conservation leading to the generalized vectorial laws of reflection and refraction

This paper considers the newly discovered laws on reflection and refraction reported in 2005 by the author. A brief review of the said discovery has been made. To give the discovery a concrete foundation and to show the efficiency of the photon theory, theoretical proof of each of those discovered laws on reflection and refraction has been offered making use of the photon theory and on further application of the principle of conservation of momentum.
