Snell's law is a ratio

Snell's law is a ratio and has no units.

Snell's law is a ratio of the angle a wave or ray of light takes going in and coming out of different materials.

SNELL'S LAW we have learnt is

`(sin\ \i\n\ \theta)/(sin\ \out\ \theta)=(n\ \(out))/(n\ \(i\n))`

Which means it is a ratio of the angle going in against the angle going out

Ratio of `(A\n\g\l\e\ \g\o\i\n\g\ \i\n)/(A\n\g\l\e\ \g\o\i\n\g\ \o\u\t)`

Which is why N has no units
