Question

__________ reflection makes the non-luminous objects visible.

Answer 1

1. The reflection of light depends upon the nature of the objects on which it falls.
2. A transparent object passes all the light through it that falls on it.
3. An opaque object absorbs a little light and reflects most of the light that falls on it.
4. When a parallel beam of light falls on a rough surface, the different parts of the surface reflect the light in different directions, this is called diffused reflection.
5. In this case, the objects are visible without the formation of their image.
6. Thus, diffused reflection makes non-luminous objects visible.

Thus, diffused reflection makes the non-luminous objects visible.
