Question
Hello sir


Sir i want to that why laws of reflection are made?
Sir please answer clearly. Please answer please

Answer
These extremely basic questions are all answered in much better detail in ANY physics textbook, with illustrations.  You can also get this and many more of your questions on optics answered here: http://hyperphysics.phy-astr.gsu.edu/hbase/ligcon.html#c1  This is part of a larger database of information maintained at a university.  The answer to your question is simple geometry, and you can dig into it by clicking on "reflection" and related concepts after that.

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
