Define term coherence as the characteristics of laser.
Coherence:
The light from a laser is called be highly coherent that implies the waves of laser light are in similar amplitude and phase. There are two kinds of coherence, specifically as given below:
1. Temporal coherence
2. Spatial coherence
Write an expression for the force experienced by a charged particle moving in a uniform magnetic field B. With the help of a diagram, define the principle and working of a, cyclotr
CPH has mass and velocity. What is its De Broglie wavelength? Answer; since I told before, the wavelength of CPH is equal of electromagnetic wavelength when it is growing.
what is electric field
Sketch a graph showing the relationship among the magnetic field around a straight, current-carrying wire, and the distance from the wire. This is a graph of y = 1/x.
a) Amplitude : It is the main value of distance of the particle from its equilibrium position. b) Time period (T): Smallest time interval after which the oscillatory motion
Q. What is efficiency of a transformer? Efficiency of a transformer is described as the ratio of output power to the input power. η= output power / input power
Friction has several disadvantages but life is impossible without friction because friction has many benefits also.
The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole.
VELOCITY: The time rate of change of displacement of a body is known as velocity. It is represented by V ?.
Calculation of number of atoms per unit cell The number of atoms per unit cell occurs on the crystal structure and the kind of basic elements (basis or pattern unit or motif) t
