Whenever a ray of light passes through a lens (except when it passes through the optical center) it bends. The bending of light rays towards the principal axis is called convergence and bending of light rays away from the principal axis is called divergenc..

Gear systems are very efficient at transferring energy. Some gear boxes are 95% efficient i.e., they only waste 5% of the energy they transfe..

Let us consider a situation where the force is acting along the X-axis and the magnitude of the force is varying with position 'x'. Thus, as the ball moves, the magnitude of the work done by the force, on the ball, changes. The adjacent graph shows the plot of a one dimensional variable ..

>The amount of heat generated in a conductor of resistance 'R', when current 'I' flows through it in a given time 't', is given by I 2 Rt. Electric power is said to be one watt if a potential difference of one volt causes a current of one ampere to flow through a conductor. The magnetic f..

First, the data of concentrations versus time is obtained by a suitable method. Then, the data is plotted as concentration versus time. From the resulting plot, the instantaneous rates are determined by drawing tangents to curve and then calculating their slopes. The reaction rate so obtained are p..

Let two thin lenses L 1 and L 2 of focal lengths f 1 and f 2 be placed in contact so as to have a common principal axis. It is required to find the effective focal length of this combination. Let O be a point object on the principal axis. The refractions through the two lenses a..

A star is a dense cloud of hydrogen and helium gas contracting under its own gravitational pull. In all the stars hydrogen atoms are continuously converted into helium atoms and this process is accompanied by a large amount of energy. This energy is radiated in the form of heat and light. The stars..
