This video shows an electron detection event build up. https://www.youtube.com/watch?v=hv12oB_uyFs
When firing photons or electrons at a light sensitive sheet (or whatever types of detectors are used), whether directly or through a double slit, does the size and density of the marks the photons and electrons leave on the sheet, change with distance?
For instance if the sheet is closer, will it leave larger and/or more intense marks than if you moved it much farther away? Or is the size/density/intensity the same regardless of distance - 1 foot, 10 feet, a mile, etc.? If there is a difference based upon distance, what is the equation/formula/mathematical relationship that governs this?
