What is the experimental principle of the reflection and refraction of physical light
1. ** The principle of straight line transmission of light ** - Light travels in a straight line in a uniform medium. For example, shadows were formed because light traveled in a straight line. When it encountered an opaque object, a shadow would be formed in the area behind the object where light could not reach. Aperture imaging was also based on this principle. After the light emitted by each point on the object passed through the aperture in a straight line, it formed an inverted real image on the light screen. A solar eclipse was when the moon was between the sun and the earth, and the moon blocked the sun's light. A lunar eclipse was when the earth was between the sun and the moon, and the earth blocked the sun's light that shot toward the moon. These astronomical phenomena, as well as the phenomenon of people in front blocking the line of sight of people behind them, were all manifestations of light traveling in a straight line. 2. ** Light Reflection Principle ** - When light travels to the interface between two media, part of the light will return to the original medium and continue to travel. This phenomenon is called light reflection. It could be simply understood by Huygens 'principle (although this principle had certain limitations). Huygens' principle pointed out that every point on the spherical wave surface (surface source) was a sub-wave source of a secondary spherical wave. The speed and frequency of the sub-wave were equal to the speed and frequency of the primary wave. The envelope of the sub-wave surface at each time was the total wave surface at that time. The reflected ray, the incident ray, and the normal line are in the same plane; the reflected ray and the incident ray are on both sides of the normal line; and the reflection angle is equal to the incident angle. 3. ** The principle of light refraction ** - When light enters another medium at an angle from one medium, the direction of transmission will deviate. From a microscopic point of view, the wave was refracted due to the change in the medium. For example, in an experiment, a card marked with an arrow was placed behind a cup of water. After adding water, the direction of the arrow changed. This was the phenomenon of light refraction. Different colors of light would bend to different degrees when refracted, and the degree of bending was determined by the length of the light. For example, sunlight would be refracted when passing through rain particles. Red light would bend the most, followed by orange and yellow light, and so on. Purple light would bend the least, thus forming a rainbow. When light enters a light-dense medium from a light-sparse medium, the angle of refraction is greater than the angle of incidence. When the angle of incidence increases to a certain extent, the phenomenon of total reflection will occur, that is, the refracted light will disappear and all will be reflected back into the original medium.
