Hmm, I’m not actually sure. Are we also ignoring refraction and reflection because the path is straight between those? If we’re talking discrete photons, you may be correct about each segment in its path being perfectly straight, but I’m not a theoretical physicist.


Most physical objects I encounter are the same color up close that they are far away…
Edit: ITT, people who completely misunderstand my point downvoting me and being pedantic
