We can deduce the law of refraction of light from Fermat's shortest path length principle: nsinA = n'sinA '. Proponents of the fluctuation of light have posed the following inconveniences to light microparticles: If it is assumed that light is a particle, its motion follows The principle of the minimum action, δ∫pdl = 0. If p = mv, then δ∫vdl = 0, this leads to the following law of refraction: nsinA '= n'sinA, which is a clear violation of experimental facts. Even considering the theory of relativity, for free particles, p = Ev / c ^ 2 still holds, E is the energy of the particles, and from one medium to another medium, E does not change, so we still get δ∫vdl = 0, How to solve this contradiction?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

i really don't know how to solve this problem.
