Absorption Right Ans - in terms of light and lenses-when a ray of light
enters a lens some of the light will not completely travel through the lenses.
Angle of deviation Right Ans - the angle a ray of light is changed from it's
original path, designated by "d"
Diffuse reflection Right Ans - a feflection from a rough surface-the
reflection does not produce a clear image
Angle of incidence Right Ans - the angle which a ray of light makes with the
surface of a refracting medium, designated by "i"
Reflection Right Ans - the return of light waves from a surface, the
production of an image
Angle of refraction Right Ans - the angle created when a ray of light passes
from one medium into another. designated by "r"
Specular reflection Right Ans - the forming of a clear image when light
strikes a surface
Critical angle Right Ans - the angle of incidence beyond which rays of light
passing through a denser medium to the surface of a less dense medium are
no longer refracted but totally reflected.
3 things that can happen to a ray of light when it passes through a lens
Right Ans - absorbed , reflected, refracted
Monocular PD Right Ans - Pupillary Distance : each eye is measured
separately from the center line of the face. two measurement, two numbers,
but mono because its one eye at a time
Binocular PD Right Ans - pupillary distance: the measurement is taken
from the center puppil to center pupil. one number, one measurement but it's
bino because it encompasses both eyes into one measurement
, Eyewear can be divided into what three categories Right Ans - dress, sport
and safety
What is transposition Right Ans - changing of a prescription from plus
cylinder to minus cylinder or the other way around. it does not affect the
powers of the prescription
What type of image is formed by a minus lens Right Ans - virtual
A plus lens does what to light rays that pass through it Right Ans - makes
them converge
What does the term critical angle of a material mean Right Ans - the ray of
light is striking the surface at an angle so that the ray is refracted along the
surface of the lens
A minus lens with the optical center moved up creates Right Ans - base
down prism
Base up prism Right Ans - projects an image of the object downwards,
bends light towards the base, bends light rays away from the apex
The wavelengths of visible light range approximately from Right Ans - 400-
720 nanometers ROYGBIV (left low frequency)
Blue-green Right Ans - the wavelengths that ae the most pleasing to the eye
are
Dispersion Right Ans - the breakdown of light into its component colors is
called
Optical center Right Ans - the point on a lens which a ray of light will pass
through without being deviated . the point of no prism in a lens. in minus lens,
it is the point where the two prisms meet apex to apex, in a plus lens it is the
point where the two prisms meet base to base
The lower the abbe number, the Right Ans - more the chromatic aberration
