Question

Experiments effectively equivalent to the electron double slit have been conducted in different, novel ways, producing obvious maxima and minima. Often the point is stressed that the intensity is extremely low. Why is this fact emphasized so much? How low is low enough to make the point?

Short answer

The reason for this is because if the intensity is low enough for many "particles" are not present in the equipment at the same time, the inference that each impact with itself becomes much stronger.

Step-by-step solution

The double slit experiment

The double slit experiment is a well-known physics demonstration. It illustrates, with unequalled weirdness, that small atoms and molecules have a wave-like quality to them, and it implies that simply viewing a particle has a huge influence on its functioning.

Explanation

When designing the laboratory apparatus for the double slit experiment, it is critical to ensure that the intensity of the incoming electrons or photons is as low as feasible.The goal is to examine the wave nature of this particle (electron in our example), such that this incoming wave can interfere among itself after exiting the two slits.As a result, if electrons are waves, then when they are assaulted on the screen one at a time, an individual electron has the ability to interfere with itself.

This is accomplished using a minimal laser; otherwise, it may be argued that the constructive interference on the screen is a result of some kind of complicated or chaotic classical activity.Concerning the second half of this question, how do you characterize the phrase "low intensity?" This would be the ideal research arrangement if only we could set up the research so that one particle arrives on the screen at quite a moment.
