Asses the impact of the development of the electron microscope on our understanding of the cell and it’s role in cell theory. Since the invention of the electron microscope in 1928 scientists have been able to study the ultrastructure of cells‚ that is‚ parts smaller than what can be seen with a light microscope‚ otherwise known as organelles and their functions. Light microscopes had been developed to a point where the quality of the lenses was not limiting the detail in the image‚ the main

Aim:- To investigate the effect of changing the temperature of glycerin on the index of refraction. In this experiment I will be using a simple method‚ which needs the following materials 40ml of glycerin in a beaker‚ protractor‚ a pencil‚ a laser‚ a paper to draw boundaries‚ circular plastic plates‚ hotplate‚ ruler and a digital thermometer. In this experiment 1 trial will be conducted for glycerin with 70 Celsius degrees ‚66‚62‚58‚ and another trial with 10 Celsius degrees. Scientific Background:-

The Cube: Geometrical Shape or Death Machine? The Cube a movie directed by Vincenzo Natali and released in 1997‚ depicts six strangers awakening after being abducted in the middle of the night‚ trapped inside a giant mechanical cube fighting to escape‚ for survival‚ and against their own inner-demons. Each of the characters in the movie have drastically different personalities and a different skillsets. As the story unfolds‚ they understand that each individual skill is needed to help them escape

The Ponzo Illusion is a geometrical optical illusion which suggests that the human mind judges an object’s size based on its background. This illusion takes place when two lines that are equal in size are placed between converging lines and seen as being different lengths. A visual example of a Ponzo Illusion would be a railroad track with a sunset as the background. The perpendicular lines that run vertical outside of the horizontal ones give the illusion that the tracks may actually be going

EXPERIMENT 7 EXPERIMENT 7 EXP 7: THE FOCAL LENGTH OF A CONVEX LENS BY GRAPHICAL METHOD EXP 7: THE FOCAL LENGTH OF A CONVEX LENS BY GRAPHICAL METHOD ABSTRACT The report is about the focal length of a convex lens using the graphical method. The aim of the report is to determine the focal length of a convex lens using the graphical method. The focal length of an optical system is a measure of how strongly the system converges or diverges light. The method that was used was experimentation

“Mirage: An optical effect that is sometimes seen at sea‚ in the desert‚ or over a hot pavement‚ that may have the appearance of a pool of water or a mirror in which distant object are seen inverted‚ and that is caused by the bending or reflection of rays of light by a layer of heated air of varying density.”(Merriarn-Webster’s Medical Dictionary) Imagine yourself walking alone in the desert‚ you haven’t drink any water for a long time‚ you were tired‚ thirsty and exhausted.

Rock art documentation by using multispectral is becoming popular in the cultural heritage domain. Multispectral is a camera with multi-lenses and sensors‚ which can take pictures of an object by multi-wavelength at the same scene. Usually‚ the advantage of using multispectral is it can detect an invisible object because it equipped with Near Infra-red (NIR) band‚ which is useful in reflecting the invisible spectrum. However‚ in the application of rock art documentation‚ multispectral is only focused
