Principle Ray II. Preliminary on the object side of the lens ray II heads toward the plane of the lens along a line that is parallel to the principle axis of the lens. At the plane of the lens it suddenly adopts a path that takes it directly away from the focal point that is on the same side of the lens as the object. If you outline that ray straight back the trace-back line passes through said focal point.
Consider the 4-f system below where an object is placed at the input plane and is illuminated by a plane wave The object to the right is placed in the input plane where b
Draw a graph showing the variation of potential energy of a p of nucleons as a function of their separation. Show the regions in which nuclear force is (i) attractive, and (ii) rep
Q. What is ionisation potential energy? For hydrogen atom the energy necessary to remove an electron from first orbit to its outermost orbit (n=∞) is 13.6-0 = 13.6eV. This ene

An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) Momentum but not energy b) Neither momentu
It is the property of a material by virtue of which it allows itself to be magnetized. Permeability varies from material to material depending upon the saturation and temperature.
Hooke's law is valid for only little deformation. Hooke's principle describes that the extension produced in the wire is directly proportional to the load applied within elastic l
