Torque is a measure of the force that can cause an object to rotate about an axis. In this lesson, our JC2 Physics PMC tutor explains the method to find the torque of a rotating coil.
Our JC2 Physics PMC tutor illustrates the occurrence of diffraction at a single light. Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit.
Alternating current is an electric current which periodically reverses direction. In this video, our JC2 Physics PMC tutor carefully explains how to use the alternating current diagram to aid in answering the question.
In this video, our JC2 Physics PMC tutor elaborates on energy levels and spectral lines. Energy levels are the particular energy values that electrons around a central nucleus (in an atom) have. Spectral lines are often used to identify atoms and molecules.
Our JC2 Physics PMC tutor in the video discusses the emission line spectrum and the absorption line spectrum. Absorption lines are usually seen as dark lines, on a continuous spectrum while the emission spectrum of a chemical element is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.
Simple harmonic motion is a special type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. In this video, our JC2 Physics PMC tutor illustrates this motion in a graph.
Simple harmonic motion is a special type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. In this video lesson, our JC2 Physics PMC tutor explains the concept in a graph.
A fringe separation is the distance between any two consecutive bright fringes or two consecutive dark fringes. In this video, our JC2 Physics PMC tutor guides us through how to approach questions under this topic.
