Introduction Spectrophotometer is an optical instrument that measures and shows how much light energy is transmitted by a substance in solution at different wavelengths of radiant energy. Light passes into a monochromator where only a very narrow range of wavelengths can pass through. From there‚ light is transmitted through a sample solution‚ and on to a phototube where the light energy is converted to an electric current that is registered on a meter. To measure the amount of light absorbed

Experiment title: Spectrophotometer and its function. Introduction Measurement of the amount of light to the absorbance is called spectrophotometer. Spectrophotometer used to test the sample by passing through the light it’s worked to measure the light that passing through. Biological substances such bromophenol blue and methyl orange‚ are the common substances to be used in testing of interaction of substance with the light. These solutions called pigments where they usually can absorb the visible

this new occupation came with long hours and shameful pay. “In 1890‚ the average working woman was twenty-two and had been working since the age of fifteen‚ laboring twelve hours a day six days a week and earning less then $6 a week.” (Roark et al. 590). This is a perfect example of how industrialism may have given the working woman more employment opportunities‚ but still restricted them from equal rights. By 1890 women transitioned from domestic work‚ to factory work and then to the office.
