In partial refraction and partial reflection under the wave theory of light, does the following apply?

Question

angle of reflection = angle of incidence + angle of refraction.

is this always true or only for certain situations?

Answer 1

no, refraction is going THROUGH a medium.

reflection takes place only at a boundary.

Answer 2

i don't think of you may wisely say that it extremely is the two. it may often times be stated performing in techniques such as one or the different, yet it extremely is not comparable component as asserting it extremely is one or the different. there's a ordinary decrease nevertheless, to how wisely you may answer this question. it extremely is achievable to define the circumstances under which mild will behave extra like a particle, or like a wave. although those circumstances are defined commonly by the act of watching the mild itself. this implies you may not, by definition, straight away word mild as something yet a particle, wherein case it is going to reason effects according to what you will assume from a particle. yet you may word the effects it has while performing like a wave, as long as you do not look straight away because of the fact the mild itself. because of the fact of course, in case you look on the mild itself you will discover that it extremely is a particle... and then its effects in simple terms isn't wavelike... the important component approximately this definition is that it does not say what the actual nature of light is, the two particle like or wave like, it in basic terms defines the circumstances under which we are able to assume to make sure it doing one or the different. it extremely is held to be impossible, actual impossible, to observe its actual nature, even though it extremely is.
