L - Light Facts
A form of energy that we can see.
What is light?
The shape of lens that brings parallel light rays to a single point.
What is a converging lens?
The term for a diverging mirror.
What is a convex mirror?
The change in speed of light as it enters a new material, due to density differences.
What is Refraction?
Label the parts of a converging lens ray diagram.
MUST HAVE 5 LABELS: principal focus, secondary focus, axis of symmetry, principal axis, optical centre
The production of light as a result of high temperature.
What is incandescence?
The type of image that a convex lens creates, when the object is beyond 2F'.
What is an inverted, real image?
The centre of the sphere whose surface has been used to create the mirror.
What is the centre of curvature?
What is the critical angle?
Label the parts of an eye.
MUST HAVE 6 PARTS: iris, pupil, cornea, lens, retina, optic nerve.
The parts of the visible spectrum.
What is red, orange, yellow, green, blue, indigo, and violet?
The type of image formed when an object is located at F' of a convex lens.
What is no clear image?
Shape of mirror that shows objects larger and inverted (when behind the focal point).
What is a concave mirror?
When red and green light interact, we get this colour.
What is yellow?
Complete the refraction diagram.
16.5o
The colour of light depends on this.
What is the wavelength?
It always forms a virtual image.
What is a diverging lens?
This is why stores use convex mirrors against shoplifting.
Convex mirrors show objects smaller and more can be seen.
It is an object that splits white light into the colours of the visible spectrum ("rainbow colours")
What is a prism?

The study of light, its physical properties and interactions.
What is Optics?
The imaging rule that applies to ALL lenses.
What is the 3rd rule?
OR
What is a ray through the optical centre?
It is the line that goes through the center of a curvature in a lens.
What is the principal axis?
The situation when the angle of incidence is greater than the critical angle.
