1. Optics and Light
Lesson 1

2. Curricular Outcomes for Today’s Lesson:
Investigate to determine how light interacts with transparent, translucent, and opaque materials.
Classify natural and artificial sources of light as incandescence, fluorescence, phosphorescent, chemiluminescent, or bioluminescent.

3. Luminous vs. Non-luminous Objects
Part 1
Luminous vs. Non-luminous Objects

4. Luminous Examples: Definition: Light bulb, lightning, sun, candle.
An object that produces light.

5. An object that does not produce light.
Non-luminous
Examples:
Moon, most objects.
Definition:
An object that does not produce light.

6. Transparent, Translucent, and Opaque
Part 2
Transparent, Translucent, and Opaque

7. Materials that allow light to pass through freely.
Transparent
Examples:
Glass, clear plastic.
Definition:
Materials that allow light to pass through freely.

8. Translucent Examples:
Thin or light-coloured fabric, stained glass, coloured plastic, tissue paper, leaf.
Defintion:
Materials that allow some light to pass through, while some is reflected or absorbed.

9. Opaque
Examples:
Wood, metal, stone, thick or dark-coloured fabric, thick plastic.
Definition:
Materials that do not allow any light to pass through.

10. Part 3 Types of Luminous sources:
Incandescent, Fluorescent, Phosphorescent, Chemiluminescent,
and Bioluminescent

11. Incandescent Examples: Sun, traditional light bulb, candle.
Definition:
Emitting light because of high temperature.

12. Fluorescent Examples: Neon sign, fluorescent light bulb/tube.
Definition:
Emits light while receiving energy from another source.

13. Glow-in-the-dark objects.
Phosphorescent
Examples:
Glow-in-the-dark objects.
Definition:
Emitting light for some time after receiving energy from another source.

14. Chemiluminescent Examples: Glow sticks, glow bracelets. Definition:
Emitting light because of a man-made chemical reaction.

15. Emitting light because of a naturally-occurring chemical reaction.
Bioluminescent
Examples:
Jellyfish, fireflies.
Definition:
Emitting light because of a naturally-occurring chemical reaction.
