Description
"Reflection of Light" Light Phenomenon PPT Courseware 14
1. Light source
Objects that can emit light are called light sources
practise
1. Which of the following objects is a light source ( )
A. Metal plate with smooth surface;
B. Working light bulb;
C. Unlit candle;
D. Mirror.
2. Light propagates along straight lines
Condition: Light propagates in a straight line in the same (uniform) medium.
3. Speed of light
speed of light in vacuum
V=3×108m/s
The speed of light propagating in air
V=3×108m/s
4. Light
Use a straight line with an arrow to describe the path and direction of light propagation
Reflection phenomenon of light:
When light is emitted from one medium to the interface of another medium, part of the light returns to the original medium, causing the propagation direction of the light to change. This phenomenon is called reflection of light.
law of reflection of light
⑴Reflected light and incident light are separated on both sides of the normal line
⑵The reflection angle is equal to the incident angle
⑶Reflected light, incident light, and normal are on the same plane
practise
1. Draw the incident ray based on the given reflected ray and indicate the incident angle.
6. Specular emission and diffuse reflection
Conclusion: Both specular reflection and diffuse reflection follow the law of light reflection.
