Answer #1

Snell's law otherwise called as Law of refraction describes the way how light passes from one medium to the other.

Which means when light passes from air(rearer) to wood (denser) the incident Ray is refracted with a small deviation from the Ray of incidence.

Carpenters or crafts men often deal with different kinds of medium to make products.therefore it is very essential for them to be aware of behavior of the light wave on the material they use for work.

By Snell's law N1 Sin x1 = N2 Sin x2

Therefore the expected angled can be marked more accurately by using a protractor.
