why is that when we talk about light passing through a glass,it suffices to consider the top and the bottom surface alone............we don care about whats'happening between them (i mean its thickness)

Question

ask this question to ur professors very few will knw the right answer

anonymous · Answer

well i think its more similar to the bubble as here outer surface and inner surface is there along with thickness and they give the ans that thickness is to be there which is a lil ealastic and applies pressure against the inner surface and also applies the pressure against the atmospheric presure. now the thing came what kind of pressure is exerted so its a molecular force of membrane

I'm not sure I understand the question, but light only refracts when it encounters a change in the density of the material it is passing through. The density inside the glass from one point to the next is the same, so no refraction occurs inside the material. The thickness of the glass does change the path of the light though, so it does matter in some respect.
