Example Sentences

But need the angle of reflection be equal to the angle of incidence in any universe?

From Literature

It’s as though the work confesses frankly that to catch honest sight of a child requires an imaginary angle of reflection.

From New York Times

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence or the angle of approach so to speak is equal to the angle of reflection.

From Golf Digest

Strictly speaking, the reflected beam has a wavelength longer than the angle of reflection and the spacing of the horizontal planes should allow according to Bragg's law, Vos says.

From Science Magazine

If we draw a line from the point of incidence B, perpendicularly, to the mirror, it will divide the angle of incidence, from the angle of reflection, and you will see that they are equal.
