A dry cell is a battery that converts the chemical energy inside it to electrical energy. Dry cell batteries consist of a sealed chamber... View Article
An alternating current is preferred over a direct current to measure the conductance of a solution because DC causes the polarization of... View Article
The central fringe in Newton’s rings is dark in the case of the reflected system because the air film thickness formed at the centre between the... View Article
Light and other types of electromagnetic waves are considered transverse waves. These waves travel through a vacuum as they do not need a medium... View Article
The period or the time is taken for one oscillation by a pendulum can be calculated using the following formula: where T is the time period,... View Article
From the kinetic gas equation, we know the following relationship: The above equation signifies the relationship between kinetic energy and... View Article
A Zener diode is a unique diode that not only allows current to flow in the forward direction but also, in the reverse direction on reaching the... View Article
Light behaves prominently like a wave, but it is also considered to be comprised of tiny packages of energy known as photons. Photons carry a... View Article
Each beam of light has its own particular wavelength and is slowed differently by the glass. Violet light has a shorter wavelength; hence, it is... View Article
To find the acceleration of the pendulum, firstly calculate the time taken for one oscillation (T) by the pendulum by dividing the total time by... View Article
Young's modulus is the measure of stiffness or rigidity of a material. The Young’s modulus is also referred to as the modulus of elasticity. The... View Article
