A physics student enhanced a classical microscope by replacing the traditional eyepiece with an ocular camera, enabling direct imaging of microscopic samples. The camera's sensor has a width of 25 mm and individual pixels measure 3.5 μm × 3.5 μm. If a microorganism structure appears with a length of 100 pixels in the captured image, what is the actual length of the microorganism structure in μm? Consider the magnification of the microscope as 100.
A pair of lenses is used to focus an object with a height of 0.500 mm on a wall. The object is 1.50 m away from the wall, 15.0 cm to the left of a -18.0 cm lens. A second lens with focal length f is placed at a distance d to the right of the first lens. Calculate f and d if the image on the wall is 2.00 mm tall.
