Second Grade Physics, People's Education Version, Reflection of Light Notes
1. ** Light reflection phenomenon ** - It was possible to see objects that did not emit light. The blackboard's "reflection" was a reflection of light. - "Description: When light travels to a different medium, it changes its direction of transmission at the interface and returns to the original medium. 2. ** The law of light reflection ** - ** Two angles are equal **: Reflection angle is equal to incident angle (measure the angle between the incident ray and the normal line, and the reflected ray and the normal line; change the incident angle many times and measure the corresponding reflection angle.) Note that when you state the conclusion, you must say that the reflection angle is equal to the incident angle, not that the incident angle is equal to the reflection angle. If it was found that the reflection angle was not equal to the incident angle, but the sum of the reflection angle and the incident angle was 90°, the reason might be that the angle between the reflected (incident) light and the mirror was mistaken as the reflection (incident) angle. The reason for multiple measurements was to avoid chance and make the experimental conclusion universal. - ** Two Lines Separated **: The reflected light and the incident light are separated on both sides of the normal line (Special situation: When the incident light is vertical to the mirror, the reflected light, the incident light, and the normal line will be in the same straight line, that is, vertical incidence, and the three lines overlap). - ** Three-Line Co-Plane **: Reflected light, incident light, and normal are in the same plane (This can be verified by rotating the F-side cardboard backward, and no reflected light can be seen on the NOF side cardboard. If the NOF cardboard had not been rotated backward, the reflected light path could not be displayed on the NOF. The reason might be that the cardboard was not vertical to the flat mirror. The function of the cardboard included displaying the light path, verifying whether the reflected light, the incident light, and the normal were in the same plane. - ** Reversible Light Path **: In the reflection phenomenon of light, the light path is reversed (for example, if the light enters along Bo, the reflected light will exit along UA. In all light phenomena, the light path is reversed, but the reflection law is mainly the first three."Reversible Light Path" is a common law in many light phenomena). 3. ** Two reflections ** - ** Reflection classification ** - ** Mirror Reflection **: The reflective surface is flat and smooth. A set of parallel incident light rays, and the reflected light rays are parallel. For example, a smooth blackboard would "reflect light", and water would walk in the dark under the moonlight (referred to as "bright water"). - ** Diffuse Reflection **: The reflective surface is rough. A set of parallel incident light, and the reflected light spreads in all directions. He could see non-luminous objects from all directions, and the places where the moonlight was shining were the places where the ground was shining (referred to as "dark water"). Pay attention to mirror reflection and diffuse reflection. Every ray of light obeys the law of reflection. - ** Reflection application ** - ** Corner Reflectors **: 1. Characteristic: The two reflective surfaces are vertical, and the light passes through the corner reflective device. The final reflected light is parallel to the initial incident light; 2. Usage: bicycle tail light. - ** Reflection dynamic change problem ** - (1) The mirror moves along the mirror surface: the reflected light does not change; - (2) Mirror translation along the normal line: the incident point, the reflected light, and the final spot translation; - 3. Mirror rotation: the mirror rotated by 0, the normal rotated by 0 in the same direction, the reflected light rotated by 2, and the angle between the reflected light and the incident light increased (decreased) by 2; - 4. Rotation of the incident ray: The incident ray is close (far away) from the normal line, and the reflected ray is also close (far away) from the normal line, and the angle between the incident ray and the emitted ray is reduced (increased) by 2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
