Monochromatic : light that is allowed to pass through a single slit to produce coherent light
LASER : an acronym for light amplification by stimulated emission of radiation
Polarization : a property of waves that can oscillate with more than one orientation. May be achieved by reflection, double refraction, selective absorption and scattering
Focal Length : the distance from the optical center of the lens to the principal focus
Light : an electromagnetic radiation that is visible to the human eye and is responsible for the sense of sight
Magnification : the ratio of the size of image to the size object
Illumination : the amount of light falling on a unit area of a surface
Dispersion : the splitting of white light into its constituent colors
Camera : man’s answer to the eye’s inability to produce a permanent record of the image formed at the retina.
Optics : the study of light and its properties
LASIK : It is commonly referred to as laser eye surgery, and is a type of refractive surgery for the correction of myopia, hypermetropia and astigmatism.
Myopia : the medical term for nearsightedness
Opaque : an _____ body does not transmit light at all
Ray : a straight line segment with an arrow on one end indicating the direction in which light is travelling
Rayleigh : scattering that occurs when the scattering particles are small compared to the wavelength of light interacting with it
Specular : reflection from smooth surfaces
Telescope : a device that enables us to see distant objects
Mirror : any surface that is smooth enough to produce regular reflection of light incident upon it
Interferometer : a measuring device that measures the wavelength of light and the diameter of stars
Reflection : the turning back of light into the same medium after striking a surface
Refraction : the change in the velocity of light when it passes from one medium to another of different optical density
Mie : scattering that occurs when the particles are much larger than the wavelength of light
Visual Acuity : the clarity of vision or sharpness of vision
Diffraction : the bending of light around an obstacle and subsequent spreading of light waves into the region behind the obstacle
Iridology : the study of the iris of the eye
