Activity 16.4 Class 8 Science Chapter 16 Solution

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.

 

 Activity 16.4 Class 8 Science Chapter 16 Solution

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.
