what are the conditions required for regular reflection?
Answers
1. Regular and smooth surface,
2. A source of light,
3. A person or screen to observe the reflected light rays.
The light reflection is the returning back of light waves in the same medium on meeting a reflecting surface , and the surface at which the reflection takes place is called the reflecting surface .
The light reflection is classified according to the nature of the reflecting surface into the regular ( uniform ) reflection , and the irregular ( non-uniform ) reflection .
The reflections of light are usually caused by the shiny things , such as the mirrors that show a reversed image of whatever is placed in front of them , The image seems to be as far behind the mirror as the object is in front of it .
The mirrors are very smooth polished pieces of metals or plastic which reflect all the light that falls on them , and the reflection appears to be behind the mirror , The surface of a clean mirror causes regularreflection , while the dirty mirror surface causes irregular manner .
We use the mirrors when checking our appearance or driving , They also play an important role in the telescopes , the microscopes , the cameras , and other optical ( light-based ) instruments .
Not only the mirrors make the reflections of light , Most objects reflect some of the light that falls on them , we see familiar objects like the grass , the trees , and the sky only because they reflect the light fromthe Sun into our eyes .
