Static refers to bodies at rest or forces that are in equilibrium. Electrostatics is a branch of physics that deals with electric charges at rest.... View Article
Holography, radio antenna arrays, optical coherence tomography, optical interferometers and radio telescopes are based on coherent light.... View Article
Two or more capacitors are said to be in parallel when they are connected between the same two points so that on applying a potential difference... View Article
The k is the relative permittivity of the material between the capacitance. The value of k=1 for free space and k>1 for other material. The... View Article
Two sources are said to be coherent if they have the same wavelength, frequency and a constant phase difference. The phase difference between the... View Article
Circular motion is the motion of the object along a circular path. Simple harmonic motion is the projection of circular motion onto one axis.... View Article
The central maximum is the brightest central portion of the diffraction pattern. The central maximum is the widest and has the maximum intensity.... View Article
For constructive interference, the phase difference between the two waves should be an even integral multiple of p. i.e., F = 2np The path... View Article
A motion that repeats itself again and again at regular intervals of time is called a periodic motion. All oscillatory motions are periodic... View Article
These are the important properties of the magnet Magnets will attract ferromagnetic substances Like poles of the magnet repel each other and... View Article
The electrostatic force is a non-contact force. When two objects are rubbed together the electrons flow from one body to another. This results in... View Article
The working principle of the capacitor is that the capacitance of the conducting plate increases when an earthed conducting plate is brought near... View Article
Spring constant is a measure of the stiffness of the spring. If the thickness of the wire is increased then the spring constant increases.With an... View Article
The capacitive reactance of the capacitor will decrease when the frequency of voltage is increased. Consequently, there will be an increase in current.... View Article
