The discussion centers on the discreteness of light, specifically addressing the nature of photons as packets of energy. It is established that photons do not possess a defined spatial location or extent, which negates the notion of space between them. The conversation highlights that while photons can be counted in experiments involving their interaction with electrons, this does not imply they have spatial dimensions. Thus, the concept of continuity in light remains intact, as photons are fundamentally energy subdivisions rather than spatial entities.

Deepak K Kapur said:Is there any space between the constituent photons of light?
Thanks for the answer.jtbell said:This is not a meaningful question, because photons are not defined as having any particular spatial location or extent. They are not a spatial subdivision of a "chunk" of light, but instead, a subdivision in terms of energy.
