Types of Reflection

Q. In regular reflection, all reflected rays are parallel to each other for parallel incident rays but in diffused reflection, the reflected rays are not parallel to each other for parallel incident rays.

Does diffused reflection means the failure of the laws of reflection?

1. Yes, it doesn't follow the law.

2. No, it does follow the law.

3. For few cases, it follows

4. It undergoes refraction.

Q.

Why can we see our reflection on a polished metal surface or on a mirror but not on a rough surfaced stone or even on a crumbled piece of paper?

Q.

When we hold a mirror in sunlight, we see a bright patch of light on the wall opposite to the mirror. Why does this happen?

1. Due to reflection of light

2. Due to the polished surface of the mirror

3. Both A and B

4. Due to scattering of light

Q.

Which type of reflection will take place when light is incident on a highly polished surface?

1. Irregular

2. Regular

3. Diffused

4. Normal

Q. The line perpendicular to the surface at the point of incidence is known as the:

1. Incident ray
2. Reflected ray
3. Normal
4. Refracted ray

Q.

Give reasons 1- Diffused reflection takes place on rough surface

Q. What is irregular reflection? Give an example.

Q. What is irregular reflection? Give an example.

Q.

Which of the following is true regarding diffused reflection?

1. Light is reflected in different directions.

2. It occurs on a rough surface.

3. Light is not at all reflected .

4. Light is reflected in same directions.

Q. Which of the following materials causes regular reflection of incident light?

1. Heap of sugar crystals
2. Polished steel plate
3. Plane mirror
4. Rubber mat

Q. I am in a dark room where there's no light ( which is very dark) and a mirror. As known mirror needs light for reflection but how is it possible to reflect our shadows on the mirror even though there's no light?

Q. Which of the following statements is true regarding diffused reflection?

1. On a rough surface, light is reflected in different directions.
2. On a smooth surface, light is reflected in different directions.
3. On a smooth surface, light is reflected in the same direction.
4. On a rough surface, light is reflected in the same direction.

Q. Which of the following statements is true regarding diffused reflection?

1. On a rough surface, light is reflected in different directions.
2. On a smooth surface, light is reflected in different directions.
3. On a smooth surface, light is reflected in the same direction.
4. On a rough surface, light is reflected in the same direction.

Q.

Which of the following is true regarding diffused reflection?

1. None of these.

2. On a rough surface, light is reflected in different directions.

3. On a smooth surface, light is reflected in different directions.

4. Light is not reflected.

Q. Both a mirror and a page of this book reflect light. You can see an image in a mirror but not in the book. Explain.
