we will go through activity 16.4 class 8 science chapter 16 Light. In this activity 16.4, we will discuss irregular or diffused reflection. You should also go through activity 16.3 to get more about reflection.
Activity
· Imagine
that parallel rays are incident on an irregular surface.
· Remember
that the laws of reflection are valid at each point of the surface.
· Use
these laws to construct reflected rays at various points.
· Are
they parallel to one another?
· You
will find that these rays are reflected in different
· directions.

Observation and explanation
When light rays
fall on an irregular surface, they are reflected in different directions. The reflection
is known as diffused or irregular reflection.
This happens due to irregularities in the reflecting
surface.
Conclusion
Activity shows the irregular reflection through a surface
having irregularities.
