Document Summary

Total magnification of microscope= objective lens x ocular lens. Absorbance(a)= -log(t) where t is transmittance expressed in percentage. Log(t)= log(io/i) where io is the incident light and i is the transmitted light. for clear samples. Io=i, 100 percent transmittance means all light passed through the solution. 100 percent absorbance means no light is passed, all absorbed. Cu=cd/d where cu= original concentration and cd diluted conc and d dilution factor. Dilution= vol of original sol/ vol of ori sol + vol of solvent added. Resolution ( r ) = 0. 61(wavelength)/n. a = nm which can be converted to = um. Magnification of drawing = size of the drawing/actual size of the specimen. If given the approx. measurement, use field diameter. Actual size= (if 40x then) 0. 5 times approx. measurement = mm convert to = um. Distance to mean : z= data point- mean/ sd. Cell biology is the study of how cells or parts of a cell function.
