Topical: Law of Reflection

The Law of Reflection states that the angle of reflection is the same as the angle of refraction. As illustrated in the picture.

We conducted an experiment to prove this Law.

From the data collected, (theta i), the angle of INCIDENCE, is equal to the angle of REFLECTION, (theta r).

However, not every piece of date collected successfully demonstrated the law. This could be due to parallax error and random error. The errors were not very much off anyway.

The next part of the investigation was about curved mirrors.
At first, I thought that the law would not apply.
I observed that in our experiment, we used PLANE mirrors. PLANE mirrors are not curved and hence light will hit a surface that is straight. The CURVED mirror is curved, and I originally did not think that the law would apply as it is curved.
I was wrong. The experiment proved that THE LAW OF REFLECTION STILL APPLIES TO CURVED MIRRORS. If you draw a tangent on the mirror, it will be like having a plane mirror of one part of the curved mirror.
AS LONG AS A TANGENT CAN BE DRAWN ON THE MIRROR, THE LAW OF REFLECTION WILL APPLY.
