It is found that the reflection of light, from a Surface, always take place in a well defined manner according to the rules. We call these two rules as the two laws of reflection. We must, however, first know some terms to understand and explain the two laws of reflection.
(i) The ‘Point of incidence’ and the ‘Normal’: The Point of incidence is that point on the Surface of the mirror where the incident ray falls. A line Perpendicular to the Surface, at the Point of incidence, is known as the ‘Normal.’
(ii) The incident ray and the Reflected ray:The ray of light, coming towards the mirror, is called the incident ray. Similarly, the ray of light, which turns back after ‘reflection’ from the mirror Surface, is called the reflected ray.
(iii) Angle of incidence and Angle of Reflection:The angle between the incident ray and the normal at the point of incidence, is known as the angle of incidence. Similarly, the angle between the normal and the reflected ray, at the point of incidence, is called angle of Reflection.
(iv) The Plane of incidence and the Plane of Reflection: The Plane, defined by the incident ray and the normal, at the point of incidence, is called the Plane of incidence. Similarly, the plane defined by the reflected ray and the normal, at the point of incidence, is called the plane of reflection.
The incident ray, the normal at the point of incidence and the reflected ray, all lie in the same Plane.
The angle of incidence and the angle of reflection are equal to each other.
Illustration: The incident ray makes an angle of 30 degree with the normal. Find the angle of reflection.

My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
About Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
