Answers
Answer:
Explanation:
1. Polished wooden table: Regular reflection
A smooth surface is shown by a polished surface. A smooth surface is found on a polished hardwood table. As a result, the polished table will reflect light in a consistent pattern.
2. Chalk powder: Diffused reflection
An uneven surface is one that has been covered with chalk powder. Therefore, diffused reflection will take place from chalk powder.
3. Cardboard surface: Diffused reflection
An irregular surface is also an example of a cardboard surface. As a result, a diffused reflection will occur from a cardboard surface.
4. Marble floor with water spread over it: Regular reflection
Marble floor with water spread over it is an example of a regular surface. This is due to the fact that water smoothens the marble surface. As a result, regular reflection is displayed.
5. Mirror: Regular reflection
The surface of the mirror is smooth. As a result, it will provide a regular reflection.
6. Piece of paper: Diffused reflection
Although a piece of paper appears smooth, its surface is riddled with flaws. As a result, it will provide a diffused reflection.
