Let us place now in the wave field a convex plate and examine how the straight waves are reflected from it. The parabolic arc which is placed perpendicular to the direction of propagation will reflect the waves in such a way as if they were arriving from a point source at the opposite side of the mirror, the focal point.

Az elhangzó szöveg

A hullámtérbe helyezzünk egy domború lemezt. Vizsgáljuk meg hogyan verődnek vissza erről az egyeneshullámok. A parabolaívről, amelyet terjedési irányra merőlegesen helyeztünk el, a hullámok úgy verődnek vissza, mintha a túloldalon lévő pontforrásból, a tükör fókuszából érkeznének.

Reflection of waves III.

Let us place now in the wave field a convex plate and examine how the straight waves are reflected from it. The parabolic arc which is placed perpendicular to the direction of propagation will reflect the waves as though they were arriving from a point source at the opposite side of the mirror, the focal point.
