Условие

Find experimentally the dependence of the depth of field of a camera on the aperture diameter of the objective. Give the theoretical explanation of the dependence obtained. [30] [31]

Note [30]

The [Kopelevich 1992] English version reads, “The depth of focus. Find experimentally the dependence of the depth of focus of a camera on its aperture diameter (or the stop number: 16, 8, etc). Give theoretical explanation of the dependence obtained.” The original Russian text reads literally, “Depth of field. Study the dependence of the depth of field for a photo camera on the aperture diameter of the objective”.

Note [31]

The Slovak text places here an extra problem:

  1. Superpreserves

Find a way of how to place cucumbers into a 3-liter-jar with a maximum density
