The “Electron-in-a-Box” Model of the Atom. How can the atomic energy levels be explained as quantized matter waves?. Microscopy is the technical field using microscopes to view samples and objects that can not be seen without unaided eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron and scanning probe microscopy.. Peter Harris.

Optical microscopy is the oldest type of microscope and uses visible light and a system of lenses to create an image of the sample. Alimohammed Kachwala,. 1* . Oksana Chubenko,. 1 .

AIM : T THEORY: Microscope is the most commonly used piece of apparatus in the laboratory. It produces greatly enlarged images of minute objects. LIGHT MICROSCOPE A Light Microscope can be simple or (SEM) Electron Microscopy (SEM) and TEM Scanning electron microscopy is used for inspecting topographies of specimens at very high magnifications using a piece of equipment called the scanning electr Theoretically a microscope is an array of two lenses Need of M icroscopy Living organisms, cells and their organelles which are too small to be seen with the human eye, can only be seen with the aid O'Rourke LG, Pitulle C, Hegarty BC, Kraycirik S, Killary KA, Grosenstein P, et al.
