2. Calculate the field of views using the given information: A.Scanning power objective= 5x; low power objective=10x; eyepiece= 5x; scanning power field of view (FOV)= 3.5 mm; what is the low power field of view?
3. Using the information provided, calculate the size of the objects viewed. Hint you will need to calculate the FOV. A.The cell is being viewed under high power. Scanning power objective=4x; Low power objective= 10x; High power objective= 40x; Eyepiece= 5x; Low power field of view (FOV)= 4.2 mm
5)The simulation asks you about the TOTAL magnification of when you use the 40x objective. This total magnification is based on the the amount of magnification provided by the ocular lens in the eyepiece, as well as the magnification of the objective. Based on the answer given in the simulation, what is the magnification of the ocular lens? (enter the number only) Answer value
1. Calculate the total magnification for the following: A. Scanning power objective = 5x; eyepiece =4x B. High power objective = 40x; eyepiece= 5x c. Low power objective = 10x; eyepiece= 10x
3. Observe and draw the image you see using the letter "e" slide starting with the scanning lens, then low power, and high dry. Use the circles below for your drawings. Scanning tens 10wpower high power Total magnification (not objective lens power) of each image? 4. Choose one other slide to view and draw using the low power objective lens. Remember to begin with the scanning lens, focus the specimen, center it and then move to the low power lens. G O P 9 C Name of specimen? Paramecium caudatum Total Magnification?

How does the numerical aperture of an objective lens affect resolution? Question options: Numerical aperture is the optical plane visible for each objective lens Numerical aperture decreases the amount of excess light on a specimen increasing the resolution and clarity Numerical aperture is the loss of light due to changes in density between the specimen and the objective lens Numerical aperture is a measure of the amount of light an objective lens can accept producing higher resolution and allowing smaller structures to be visualized with greater clarity
