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.
Acute angles come facing all different directions, different degrees, and even different sizes, but the one thing that they all have in common is that they measure less than 90Â°. You can use a protractor to measure the angle to be sure the angle is less than 90Â°.
