BECAUSE OF THE NEWTON RINGS AND THEN HE SAID THE GLASS PLATE IS 45 DEGREE TO MAKE TURNS.
Newton rings are Alternate dark and bright rings formed due to the presence of air film when the plano-convex lens is placed on the glass plate is called newtons rings.
The angle between the incoming ray and the glass plate is 45 degree to make turns the light rays to 90 degrees and that's why the rays fall normally on the plano-convex lens. Finally forms circular rings.
HOPE IT HELPS YOU.
