Snell’s Law Snell’s law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”. Snell’s law formula […]
Terminal Velocity Terminal velocity is the highest velocity that can be attained by an object when it falls through the air. It happens when the sum of the dragged force (Fd) and buoyancy is equal to the downward force of gravity (FG) acting on the […]
The gram formula mass of a compound is the amount of that compound that has the same mass in grams as the formula mass in atomic mass unit. An atom of each element has a characteristic mass and in like manner each molecule of a […]
Refraction Light travels in a straight line, and we are aware of that. This is true on the condition that the light rays are travelling in the same medium, having the same density throughout. What occurs when light enters from one transparent medium to another? […]

The formula for finding surface tension is articulated as, Where, T= surface tension(N/m) F = force per unit length (N) l=length in which force act(m) Surface Tension Solved Examples Solved numerical related to surface tension are provided underneath: Problem 1: Compute the surface tension of a given liquid […]
The diagram shows the fixed frame in 3-dimensional view, with 3 directions x, y and z respectively. Consider the Moving frame where x’ is moving with the primed frame with the velocity v in the x direction. The reference frames coincide at t=t’=0. Where Related […]
The Reynolds number id denoted by Re. Reynolds number is given by Reynolds Number = Inertial Force / Viscous Force The Reynolds number formula is expressed by, Where, ρ = Fluid density V = Fluid velocity μ = Fluid viscosity L = length or diameter […]
Formula of Net Force If N is the number of forces acting on a body, the net force formula is given by, FNet = F1 + F2 + F3….+ FN Where, F1, F2, F3…FN is the force acting on a body. Net force when a […]
Weight is not anything but the force gravity experiences. It is represented by W and Newton is its SI unit. It is articulated as the product of mass and acceleration due to gravity. So the weight of a given object will show variation according to the gravity in that […]
The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the […]
Gregory Newton’s is a forward difference formula which is applied to calculate finite difference identity. Regarding the first value f0 and the power of the forward difference Δ, Gregory Newton’s forward formula gives an interpolated value between the tabulated points. The interpolated value is expressed […]
Inductive reactance or simply reactance is not anything but the resistance of an inductive circuit. An inductor competes against the current in a coil which alters the direction and instantaneous magnitude. This opposition is comparable to resistance but always possesses a phase shift between voltage […]
The speed of sound is defined as the travelled by the sound wave that propagates per unit time through an elastic medium. In a perpendicular medium, the speed of the sound depends on the elasticity and density of the medium. If the speed of the […]
