Atoms should have protons and an equal number of electrons to be called an atom. If the number of protons and electrons are not equal in an atom... View Article
The light rays passing through the concave lens get refracted and the rays bend away from the principal axis. The image formed will appear... View Article
The work function of a photo metal is the minimum energy required to liberate an electron from the metal surface. The gain in the kinetic energy... View Article
Thermodynamics is the study of energy relationships involving heat, mechanical energy and other forms of energy. The development in the science... View Article
In the normal operation of the transistor, the emitter-base junction is forward biased and the collector-base junction is reverse biased. The... View Article
No, two diodes connected back to back cannot be used as a transistor. A PN diode will have equal doping on both sides, but for a transistor, the... View Article
The impulse-momentum theorem states that the rate of change of momentum of an object is equal to the impulse applied to it. This is logically... View Article
The inherent speed of an object is dependant on the inertia. The smaller the inertia, the greater the speed. When the inertia reduces to zero,... View Article
When you need accurate measurements micrometres are used instead of a calliper. The least count of the calliper is 0.1 mm while the least count... View Article
The Planck’s constant in the Heisenberg uncertainty principle is very small such that the uncertainties in position and momentum of small objects... View Article
For the photoelectric effect to occur, the energy of the photon should be greater than the work function. When the wavelength of the incident... View Article
In interference, maxima is a point where two crests or two troughs of two different waves meet each other and as a result, reinforce each other.... View Article
A backward wavefront in Huygens theory doesn’t exist because the backward propagating waves destructively interfere with all the wavelets from... View Article
Kepler's laws and Newton's laws together imply that the force that keeps planets in their orbits by continuously changing the planet's velocity... View Article
A dielectric gets polarized when placed in an electric field. The field produced due to the polarization of material minimizes the effect of the... View Article
The supposed energy doesn’t come from the electric field itself. The energy is a result of the interaction between charges and electromagnetic... View Article
Damping factor is also known as the damping ratio. Damping factor is a ratio of damping coefficient to the critical damping coefficient hence, it... View Article
