‘the reflections from the street lamps gave them just enough light'
‘We may even get more reflections as the light bounces off the surfaces again and again, some of the light escaping each time.'
‘These directed light to specific task areas, reducing glare and veiling reflections, while ambient light levels were lowered.'
‘Polarized lenses on sunglasses help to reduce glare by not allowing the polarizations that come from reflections through but allowing other light through.'

8.The conceptual operation of inverting a system or event with respect to a plane, each element being transferred perpendicularly through the plane to a point the same distance the other side of it.
‘The reflection symmetry operation, as you might expect, reflects an object with respect to a plane.'
‘If the plane contains the main rotation axis then it is usually called a vertical reflection plane; and if it is perpendicular to the main rotation axis it is known as a horizontal reflection plane.'
‘Barring rotations and reflections, there are 536 distinct solutions.'
‘There are 880 magic squares of order 4, again excluding reflections and rotations of each pattern.'
‘In this case, the cryptic notation specifies a square pattern with reflections and quarter turns.'
