Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
Superfluidity: The phenomena through which, at sufficiently low temperatures, a fluid can flow along zero viscosity. Its causes are related with superconductivity.
An alternating voltage given by v=100sin240t volts is applied across a coil of resistance 32 and inductance 100mH. Verify (a) the circuit impedance, (b) the current flowing,
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of

Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te
Lagrange points: Points within the vicinity of two massive bodies (like the Earth and the Moon) where each others' respective gravities balance. There are five, labeled L1 to
Active network:- It can be described as a network, which contains one or more than single source of e.m.f. in it.
The current is an RL circuit drops from 1.1 A to 13 mA in the first second following removal of the battery from the circuit. If L is 12H, find the resistance R in the circuit.
Recording of hologram Waves scattered from the object are known as object waves. The coherent waves reaching directly form the source is known as reference waves. When object w
The density of gasoline at 0 degrees C is 0.68 x103 kg/m3 What is the density on a hot day when the temperature is41 degrees C? What is the percentage change (+/-)?
