Be able to:
 Describe the contributions of Antonie van Leeuwenhoek and Galileo.
 Explain why light is more intense the closer to the eye the light source is
using a ray diagram.
 Give examples of materials that are transparent, translucent and opaque.
 Use a diagram to compare the three differences between regular and diffuse
reflection.
 Use a diagram and explain what the law of reflection is.
 Show what concave and convex mirrors and lenses do to light using ray
diagrams.
 Explain what happens at a focal point.
 Compare what images look like in a concave and convex mirror at a very
close and very far distance.
 Use the words density, particles and speed of light to explain why light
refracts.
 Compare what images look like through a concave and convex lens at a
very close and very far distance.
 Give examples of concave and convex mirrors and lenses.
 Explain in detail how an eye works.
 Describe the similarities between eyes and cameras.
 Explain what the difference is between near and far sightedness.
 What is white light made of.

 What the wavelength range of visible light is.
 Compare similarities and differences between incandescent, fluorescent,
chemiluminescent and bioluminescent light.
 What the primary colours are.
