Define the following
1. reclining propagation of light
2. reflection of light
3.lateral of light
4. Dispersion of light
Answers
1. reclining propagation of light
Ans. Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. ... It is because light travels along a straight line and leaves only the areas where the object interferes.
2. reflection of light
Ans. Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. ... For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.
3. lateral of light
Ans. Lateral light (from one side) can emphasise surface structures within the material, such as deeper grooves. The side facing to the light appears dark, the edge inclined towards the object is bright.
4. Dispersion of light
Ans. In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency. Media having this common property may be termed dispersive media. Sometimes the term chromatic dispersion is used for specificity.
