Students will be able to
- explain that light travels at very high speeds in straight lines,
- describe experiments to show that light travels in straight lines,
- draw lines of light,
- explain that light travels at different speeds in different media, which leads to refraction,
- recognize that white light can be separated into the colors of the visible spectrum using a prism,
- name the colors of the visible spectrum,
- describe the effect of color filters on white light.
