The figure shows a ray of light falling normally on the face ab of an equilateral glass prism having refractive index 2/3 , placed in water of refractive index 3/4 . will this ray suffer total internal reflection on striking the face ac ? justify your answer.

This is the solution to lens combination question asked in 2018 xii physics paper cbse. it was required to find out refractive index of the liquid . a symmetric biconvex lens of radius of curvature r and made of glass of refractive index 1·5, is placed on a layer of liquid placed on top of a plane mirror as shown in the figure. an optical needle with its tip on the principal axis of the lens is moved along the axis until its real, inverted image coincides with the needle itself. the distance of the needle from the lens is measured to be x. on removing the liquid layer and repeating the experiment, the distance is found to be y. obtain the expression for the refractive index of the liquid in terms of x and y.

In this video, i give the method of solution for an electrostatics question that is required to find out-work required to move a charge near a line of charge. (a) use gauss’ law to derive the expression for the electric field ( e ) due to a straight uniformly charged infinite line of charge density  c/m. (b) draw a graph to show the variation of e with perpendicular distance r from the line of charge. (c) find the work done in bringing a charge q from perpendicular distance r1 to r2 (r2 > r1). this video is for part c only

Friction in physics iit is discussed in this video lesson.

Covers total fixed cost, total variable cost, total cost . will b helpful to economics students. explained with schedule and diagram.

You can see here how the matter change its states. it is really interesting. because you can see some live examples and it will help you to understand the fact of "states of the matter".
