Define Wien's Law - The hotter an object, the shorter the wavelength at maximum emission. (The hotter the object the brighter) After a cold front passes what happens to dew point? - it drops, as cold air is typically dry Centripetal force wind - right angles to the wind, in towards the center of curvature ex. hurricanes Convection is the process that? - involves mixing in a fluid Coriolis effect - The effect of Earth's rotation on the direction of winds and currents. Define a category fi...

annular bifocal contact - A lens with distance portion ground into the center of the lens and the near portion ground into the periphery aphakic lenses - lenses designed for post-cataract fitting apical zone of cornea - the central portion of the cornea with a constant radius of curvature. Also called the corneal cap. artificial tears - medications, many of them over the counter, to treat dry eyes aspheric lens - A non-spherical lens, in which the radii of curvature increase towards th...

optic zone - the central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius - this term is generally used in reference to spin-cast soft lenses. the curvature of the posterior surface of the lens changes with the refractive power. the radius of curvature is measured at the apex of the posterior surface. steeper base curve - occurs when the posterior radius of curvature is decreased (i.e. 8.4 to 8.1 ...
