Description
"Linear Propagation of Light" PPT courseware on light phenomena
1. Light source
1. Objects that can emit light are called light sources
2. Light sources are divided into two categories: natural light sources and artificial light sources.
Discussion: Is the moon a source of light?
2. Propagation of light
1. How does light travel?
Experiment 1: How does light propagate in the air?
Spray a large amount of water mist into the air, use a laser pointer to shoot a beam of light in the water mist, and observe the path of light propagation;
(Small game: Fix a laser pointer on the classroom podium and use multiple small cardboards to receive the light spot formed by the laser from far to near, and fix the position to observe the arrangement of the small cardboards.)
Experiment 2: How does light propagate in water?
Add a small amount of milk to the water, use a laser pointer to emit a beam of light in the water, and observe the path of the light propagation;
Experiment 3: How does light propagate in transparent solids?
Use a laser pointer to shoot a beam of light into the translucent jelly and observe the path of light propagation in the jelly;
2. Describe the propagation of light (model method)
Usually, a straight line with an arrow is used to represent the path and direction of light propagation. Such a straight line is called a light ray.
3. linear propagation of light
a. Formation of shadow: When light encounters an opaque object during propagation, a shadow is formed behind the object.
b. Small hole imaging: Observation and demonstration experiments describe the characteristics of small hole imaging.
c.Solar and lunar eclipse (videos can be downloaded for students to watch)
3. Speed of light
Read page 71 of the textbook; answer the following questions:
1. Thunder and lightning happen at the same time and in the same place. Why do we always see the lightning first and then hear the thunder?
2. What are the differences in the propagation of light and sound?
3. How fast does light travel in a vacuum?
4. Are the propagation speeds in other transparent media faster or slower than those in a vacuum?
Summary of the key contents of this section
straight line propagation of light
Conditions: In the same homogeneous medium
Phenomenon: shadow formation, pinhole imaging, solar and lunar eclipses, etc.
Application: laser alignment, queuing, shooting, etc.
The speed of light propagating in vacuum: 3×108m/s
