The focal length of the lens used is calculated to be 31 mm. The lens used in the experiment was a converging lens as the image was 3. Calculate the focal length of the given converging lens based on the measurements of s and s ’ and thin lens equation. Tabulate your results (for all the three trials)

magnification on a microscope? Answer: The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece lens and the nose piece lens gives you the total number of times an object will magnified. (4 points) Score 2. Explain how to focus a microscope using the high power lens. Include any safety issues you need to be aware of.

There are 3 main parts of the microscope such as illuminating parts‚ magnifying parts and mechanical parts. The sub-parts in illuminating parts are electric lamp and iris diaphragm while the sub-parts of magnifying parts are eyepiece and objective lens. The mechanical parts consist of most sub-parts among these three such as barrel‚ arm‚ stage‚ coarse focus knob‚ fine focus knob and base. Figure 1 : Fully Assembled Optical Microscope. Illuminating
