A digital camera manufacturer may also represent the camera's resolution in PPI (pixels per inch). For example, a digital camera with a 2304 x 1728 PPI (2304 pixels wide by 1728 pixels tall) is equivalent to a 4 MP camera. 2304 x 1728 = 3,981,312 (close to 4 million) Telescope - Telescope - Impact of technological developments: Besides the telescope itself, the electronic computer has become the astronomer's most important tool. Indeed, the computer has revolutionized the use of the telescope to the point where the collection of observational data is now completely automated. The astronomer need only identify the object to be observed, and the rest is. An electron microscope can magnify an object up to 10,000,000 times! That is 5,000 times more than what a light microscope can achieve. Electron microscopes use the magnetic properties of electrons, in conjunction with Louis de Broglie's hypothesis that electrons possess wave properties, to augment magnification to a whole new level Electron microscopes use electrons __to produce a black and white picture__ on a computer screen. Resolution: Resolution is the shortest distance between two points on a specimen that can still be seen as two different points by the observer. Magnification: Magnification is how much a lens (or other optical instrument) can magnify. It is the.
