Revision Notes for Interference of Waves When light waves from two coherent sources meet at a point, they interact with each other to yield interference. Coherent sources are those two or more sources of light that produce light waves of the same color (monochromatic), the same wavelength, and a constant phase difference. When light…

Force on Moving Charge in a Magnetic Field Let us consider a positive electric charge 'q' that moves through a magnetic field (magnetic field strength B) with a velocity 'v' and makes an angle '$\theta$' with the magnetic field. Then, it experiences a force due to the field perpendicular to the velocity and t…

Logic The thought process that humans implement in reaching a conclusion is called logic. In Mathematics, we require logic to validate given statements. For example, one can say, "The sum of two non-zero and positive integers is always an even integer." One cannot tell if this claim is either true or false wi…
