This article considers the comment of Hawkes on 'The generalized vectorial laws of reflection and refraction' (Bhattacharjee 2005 Eur. J. Phys. 26 901). In order to get rid of the confusion that resulted regarding the generalized vectorial laws of reflection and refraction developed by the author in 2005, the attention of the reader is drawn to a few points in this reply. © 2014 IOP Publishing Ltd.

This paper deals with the application of the newly discovered generalized vectorial laws of reflection and refraction for making an extensive analysis of reflection and refraction at spherical surfaces. Various cases of image formation have been considered. It has been observed that, direct application of the generalized vectorial laws of reflection and refraction leads to the appropriate formula of ray optics for each of the cases considered. The analysis of the results are ultimately summed up to give birth to the generalized mirror formula as well as the generalized formula for refraction at spherical surfaces. Also by using the results obtained for refraction at spherical surfaces, the Lens makers' formulae have been finally offered. © 2011 Elsevier GmbH. Source

The theoretical study of physical science and engineering is based on many conventions that have already earned international recognition. But what is it about those conventions that have no resemblance with real-life situations? There is an urgent need to consider and remove such conventions, either with alternative replacements in compliance with real-life situations or deal with a problem where such a convention is used by alternative treatment so as to establish a bridge between theory and practice. Such attempts have been made by the author (Bhattacharjee, 2002, 2008, 2011, 2008). In Bhattacharjee, 2002, a means of removing the most misleading sign convention of geometrical optics has been pointed out with the help of vector algebra. © 1988-2012 IEEE. Source

This paper makes use of the refined unambiguous angles of incidence and refraction reported earlier by the author to give birth to a novel general expression for the dispersive power of a prism. This expression has been subsequently employed to derive interesting findings in respect of the dependence of dispersive power on: (i) the refracting angle of prisms for a particular unambiguous angle of incidence, (ii) the unambiguous angle of incidence for a particular thin prism, and (iii) the unambiguous angle of incidence for a particular thick prism. The results obtained are all novel and unlikely to be found in the traditional optical literature. As such the present contribution will enrich the long-running optical literature thereby enhancing it as well. © 2015 Elsevier GmbH. Source
