Regular and Irregular Reflection
Regular and Irregular Reflection
Reflecting surfaces
When light from the sun or any source falls on an object, we are able to see the object because the light reflected by the object reaches our eyes. Reflection by a regular surface is referred to as regular reflection. A rough surface reflects a parallel beam of light incident upon it in all directions. The small bumps and irregularities on a rough surface cause each of the light rays to reflect in different directions. This kind of reflection is called irregular or diffused reflection.
Regular Reflection
When a parallel beam of incident light is reflected as a parallel beam in one direction Regular Reflection takes place. Regular reflection of light occurs from smooth surfaces like a plane mirror or a highly polished metal surfaces. This happens because all the particles of a smooth surface are facing in one direction. Due to this the angle of incidence for all the parallel rays of light falling on it is the same and hence the angle of reflection are the same for all the rays. Since angle of incidence and angle of reflection are equal for all the rays. So the incident parallel beam will remain parallel after reflection.
Diffused Or Irregular Reflection
When a parallel beam of incident light is reflected in different directions or gets scattered Diffused Or Irregular Reflection takes place. Irregular reflection of light occurs from rough surfaces like a paper, cardboard, table etc. This happens because all the particles of a rough surface are facing in different direction. Due to this the angle of incidence for all the parallel rays of light falling on it is different and hence the angle of reflection will not be the same for all the rays. The angle of incidence and angle of reflection are equal for a particular ray. The different rays of a parallel beam are reflected at different angles,so the incident parallel beam will get scattered after reflection.The laws of reflection are also followed in the case of irregular reflection.

Students / Parents Reviews [10]
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.

8thMy 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.

8thAbout 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.

8thA 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.

7thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Barkha Arora
10thMy 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.
Shivam Rana
7thOne 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.
Aman Kumar Shrivastava
10thAbhyas 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.
Om Umang
10thIt 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.
