Definition of Snell’s Law
The refractive index between two particular mediums is equal to the ratio of speed of light in first medium and Speed of light in second medium equal to the ratio between sin <i and sin <r.
Refractive Index = sin<i/sin<r = Speed of light in first medium/Speed of light in second medium
Note: The issue of trust becomes very important in the field of education, in particular, in the institution – a kind of school that prepares people for admission to adulthood. Find an official document, where it will be said about this directly, it is impossible. However, in any university, a student will inevitably have to face such a philosophy in real life. It is very important for students to develop a trusting relationship, because without them it will be difficult, despite all the pragmatism that exists in the modern world. It is very important for any student not only to attend lectures and take exams, but also to earn the teacher’s confidence. After all, this is one of the very important components of the unwritten code of the teaching of “rules of student life” in addition to the educational program. Students are the wards of their teachers, which leads to the building of a trusting relationship. It is not uncommon for teachers themselves to conduct a so-called “lice test” among students to understand who is among them. At that moment, how exactly to earn the trust of the teacher, and it is worth dwelling in more detail.
