Two coherent sources of intensity ratio 100:1 interfere. Deduce the ratio of intensity between the maxima and minima in the pattern..

Red light of l = 650 nm from a distant source falls on a slit of 0.5 mm width. What is the distance between the two dark bands on each side of the central bright band of diffraction pattern observed on screen placed 1.8 m from the sli..

27. - The ratio of the intensities at minima to maxima in the interference pattern is 9:25. What will the ratio of the widths of the two slits be in Young's double slit experimen..

Parthenogenesis and Tissue Culture - Parthenogenesis is a form of reproduction in which the ovum develops into a new individual without fertilisation. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g., the aphid. In many..

A small amount of the sample is introduced into the mass spectrometer and is bombarded by a stream of high-energy electrons (70 electron volts (eV) or 1600 kcal/mol). When the high-energy electron strikes an organic molecule, it removes a valence electron from the molecule, producing a cation radi..

. It has four cellular elements tracheids, tracheae, fibres and parenchyma of which only xylem parenchyma is living. Xylem tracheae (or vessels) are the most active water conducting elements. Based on the pattern of lignification, they can be distinguished into annular, spiral, scalarifor..

. They found him cute because of his shining feathers with shimmering patterns displaying rainbow colors. He had a curved, cosy, and rounded body, dark liquid eyes. He had bushy little hands, complete with thumbs that cutie pie used with astonishing speed and skill. Cutie Pie became an in..
