is called specular or regular reflection. The laws of reflection are as follows: The incident ray‚ the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. he reflected ray and the incident ray are on the opposite sides of the normal. These three laws can all be derived from the reflection

A study performed by Jo-Anne Finegan in Toronto followed 88 women who had‚ had amniocentesis‚ there was an increased incidence of ear infection in this group. Finegan tested the stiffness of the eardrum and found children in the amniocentesis group were more than three times as likely to have abnormal readings. It is thought that there is a disruption of the delicate balance
