1. A line making 90 degrees to the line representing the mirror at the point where the incident ray strikes the mirror is known as the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection to the reflectlng surface at that point.
2. The angle between the normal and incident ray is called the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection
3. The angle between the normal and the reflected ray is known as the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection
4. The angle of  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection is always equal to the angle of  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection
5. When the whole sheet of paper is spread on the table, it represents one  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection
6. The  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection ray, the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection at the point of  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection and the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection ray all lie in the same plane.
7. In an image formed by a mlrror the left of the object appears on the right and the right appears on the left. This Is known as  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection
8. The  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection are valid at each point of the surface.
9. When all the parallel rays reflected from a rough or irregular surface are not parallel, the reflection is known as  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection or  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection reflection.
10. Irregular reflection is caused by the  angle of incidenceangle of reflectiondiffusedincidenceincidentirregularirregularItieslateral inversionlaws of reflectionnormalplanereflectedreflection in the reflecting surface, Iike that of a cardboard.
