Can moral principles really govern? Is a code of ethics truly enforceable by a state agency? Kentucky General Assembly mandates that the Kentucky Board of Physical Therapy promulgate,
The angle made by the ray of light in the air to that of the reference light (the normal), is the angle of incidence, and the angle made by the ray of light in the glass to the same normal, is the angle of refraction. It is the ratio of the sines of both these angles that is the refractive index of the block of glass.
The most common way to measure angles is in degrees, with a full circle measuring 360 degrees. You can calculate the measure of an angle in a polygon if you know the shape of the polygon and the measure of its other angles or, in the case of a right triangle, if you know the measures of two of its sides.
