Question covered, convex and concave lens, calculation of focal point and refraction of rays, focal length, principle axis, converging and concave lens, optic center
It wasnt that interesting but i understood the concept
It was hard and irritating to understand the logics
Plancks constant, what does it represent, relation to plancks energy formula, black body radiation, joules x seconds and waves/second relation
It was interesting to know how constants are used to define energy
It was extremely hard to understand the formula and relate the constant to real terms
Energy, work and power, formula relation, meaning of each concept, visualized these 3 concepts using real life examples, formula of kinetic and potential energy, how are 3 of them related
It was interesting, i understood the concept clear and got a sort of relevance of the concepts in real life
It wasnt hard as videos helped me out
