Experiment 9- Thin Lenses Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging

Snaps will be submitted separately. 2. Describe the relationship between what you see through the eyepiece and what you see on the stage. On the stage it was not visible enough rather it looks too small‚ while in microscope it appears black and grainy. 3. Draw the image you see of the ‘e’ slide at 200x

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:-
