"Physics has always been very challenging to beginners in college when it comes to problem solving. Faculties opine that this approach is very critical for concept building and for scoring in the university exams as most of the university questions are concept and numerical based. To address this issue `Problems and Solutions’ in the field of `Optics and Photonics’ in our kitty provides concepts in lucid language with stepwise problem solving approach! The product covers the complete spectra from basic chapters like ‘Optical Instruments, Dispersion, Diffraction’ to the latest advancements like Integrated Optics, Electro optic effect, Acousto-optic effect and Nonlinear optics. At a glance concepts and formulae, at chapter beginning sets the tone for the rest of the chapter. The most appreciated feature of this book is it’s concept, principle and numerical based problems from wide array, patterned as per FAQs in university exams. Answers follow the problems section by detailed conceptual explanations and student friendly step-wise solution. Sure to click amongst the students!" - from Amzon
