Considering the constraints on resolution in digital cameras due to lens diffraction and the division of discrete pixels on the sensor, let's explore a typical point-and-shoot camera. This camera is fitted with a lens having a focal length of 15 mm and a sensor consisting of pixels measuring 3 μm x 3 μm. What is the f-number of the lens that aligns with a diameter of 1.3 cm?
