POB II: Exam II Review Chapter 6: tour of the cell Microscopy: • Microscopes provide a window to the cell. • Most important tool in cytology • Resolution has improved understanding of cells. o Resolving power – the smallest distance between two objects that allows them to be seen as distinct objects. o Resolving power of the human eye is 0.1 mm • Light microscope – uses glass lenses and visible light to form a magnified image of an object. o Resolving power of about 100 nm (.0002 mm)

Comparing Wavelengths In The Electromagnetic Spectrum Gamma rays have the smallest wavelength in the electromagnetic spectrum‚ there is only 0.03 nano meters between the peak of each wave as is shown in this diagram. There is a universal speed that electromagnetic waves travel at which is 300m/s and this means that the wave frequency depends on the wavelength. The wave frequency for gamma rays is 300/0.03=10000hz. Gamma rays are produced by violent events in the universe such as supernovas and

How does the Wavelength affect the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the

Digital presence is prevailing in today’s social scenario. To help carve a niche in the digital space‚ Social Wavelength‚ which is a Social First Digital Agency‚ does a tricky job of understanding the intricacies of running a business in a digital/social world. The joint efforts of Hareesh Tibrewala and Sanjay Mehta (present CEOs of the agency) gave birth to Social Wavelength and helped it grow big. The duo started out with their first venture “homeindia.com”‚ an Indian eCommerce venture in 1997

Claire Graham BSC 2010L November 4th‚ 2015 Effects of Light Intensity and Wavelength on Photosynthesis of Spinach Leaves By replacing the air pockets in spinach leaf disks with a bicarbonate solution and allowing the disks to sit in the solution while being exposed to different light conditions‚ we were able to observe the effects of various light intensities as well as colors on the rate of photosynthesis. As the spinach leaves photosynthesized‚ oxygen pushed out the solution and filled the intercellular

determine the wavelength and light intensity effect on the reaction rate of photosynthesis. Photosynthesis is the conversion of light energy to chemical energy in the form of organic compounds. There are two phases in photosynthesis‚ the light reaction and dark reaction. The following experiment tested only the light reaction. Photosynthesis takes place on the chloroplast‚ and the chloroplast contains chlorophyll pigments which absorb light energy. Pigments are particular to different wavelengths. The following

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best
