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.
An acute angle is an angle with a measurement between 0Â° and 90Â°, or with less than 90Â° radians. It's the smallest of six different types of angles. There's an easy way to remember that an acute angle is small: think of it as a cute angle, perhaps visualizing a cute child playing an acute angle in a play about geometry.
