in a camera, what is used to produce a real image of an object on film/pixels
the reflected waves and the incident waves have the same frequency and speed so the have the same?
if the image is bigger than the object, the magnification is greater than what?
for a distant object, the distance from the lens to the film must be:
what is used to show the direction that light waves move in
the distance from the center of the lens to the principal focus is called?
what is the line perpendicular ro the mirror called?
if the reflected image of yourself is ordinary, what mirror are you looking into?
when waves cross a boundary between two materials, what can also happen as well as refraction?
when faced with gradually declining accommodative amplitude and continued near task demands, adult patients eventually report visual difficulties that confirm as
the nucleus and the cortex are removed out of the capsule, leaving the posterior capsule, peripheral part of the anterior capsule, and the zonules intact
concerned with the measurement of optical radiation weighted by the spectral response of the eye
these lenses feature apodization technology that creates a smooth transition between distance and close up focal points that provide a quality range of vision
accommodative ability becomes insufficient for the patient's usual near vision tasks at an earlier age than expected due to environment, nutritional, disease-related or drug-induced
since the distance between the principal plane and the retina will also be the same for all refractive ametropias, the defined ____ ____ will be the same as that in an emmetropic eye.
the sensitivity of scotopic vision in dark-adapted eye is more than ____ ____ at photopic vision in the light adapted eye.
physical measurement involving radiant energy or power of the optical radiation
measure of radiant flux incident on surface per unit area
for a monochromatic light source, radiant flux (watt) is converted to luminous flux (lumen) by weighing radiometric component with
one of the problems most frequently associated with correction of anisometropia
