Conclusion

After reading pages 24 and 25 i have learned more about waves and how they react. For example, When an object or waves hit a surface through which it cannot pass, it bounces back/ The angle of incidence is the angle between the incoming wave and the imaginary perpendicular to the surface and the last thing is when a wave passes through a barrier or moves through a hole in a barrier, it bends and spreads out. All these notes i took are from the, "Science Explorer" these notes are parity good and they give a good feeling about waves. Some of the words i learned are, The bending of waves due to a change in speed is called REFRACTION, another one is, the bending of waves around the edge of a barrier is known as DIFFRACTION.
