Unit 3: Light and Optics
Vision is our most important sense. In this unit we will examine the principles
of how light is reflected and refracted, as well as how the eye works and how
we see colour.

Light and Optics Unit Objectives (or Outcomes)
By the end of this unit the student will be able to
apply the Universal Wave Equation to light (and other forms of electromagnetic
radiation)
define light, index of refraction, critical angle
determine the speed of light in various substances
draw ray diagrams indicating reflected and refracted rays
use Snell's law to determine the amount of refraction as light passes from
one medium to another
determine the critical angle
for a substance
explain the conditions required for total internal reflection
state at least 4 applications
of total internal reflection
experimentally determine the
focal length of a converging lens
state applications of converging
and diverging lenses (spectacles and other optical devices)
use ray diagrams to determine the position and characteristics images produced
by a thin lens (both converging and diverging)
use the thin lens equation to determine the position and characteristics
of images produced by a thin lens
use the magnification equation
to determine the sizes of images
do ray diagrams for simple optical device consisting of two lenses
relate focal length of a lens
to curvature, change in index of refraction, immersion in a different medium
state the regions of the
electromagnetic spectrum in order of increasing wavelength (or energy,
or frequency)
determine how the wavelength
of light changes as it goes from one medium to another
relate changes in frequency
of light to changes in refractive index (producing dispersion)
label the parts of the eye
describe the function of
each part of the eye
explain night vision, primary
colours, and dark adaptation using the properties of the retina, rods,
and cones
determine the result of
additive colour mixing
determine the result of
subtractive colour mixing
state applications of both
additive and subtractive colour mixing
Not done: relate focal length of a spherical mirror to centre of curvature
Not done: draw ray diagrams to locate images in plane and curved mirrors
