A student microscope has a 10X objective and a 16X eyepiece. A student is using the microscope to view a thin slice of an apple. The cells in the apple have a diameter of 0.12 mm. Assume a length L = 165 mm.

a. How far from the objective lens should the apple slice be placed?

b. How does the angular size of a cell when viewed through the microscope compare to the angular size of a 19 mm diameter penny at a distance of 25 cm?

Question 2:

Two converging lenses with focal lengths of 48 cm and 25 cm are 17 cm apart. A 2.3 cm tall object is 15 cm in front of the 48 cm focal length lens.

a. Use ray tracing to find the position and height of the image. Determine the image distance and image height by making accurate measurements on your diagram.

b. Calculate the image height and position relative to the second lens. Compare with your ray-tracing answers in part a.

c. Clearly mark the object, image, object distance, image distance and focal length for both the lenses.

d. Show all your calculations.

e. Write down the image characteristics of each image.
