  The main aim of this paper is to determine reflections to bijective and
non-degenerate solutions of the Yang-Baxter equation, by exploring their
connections with their derived solutions. This is motivated by a recent
description of left non-degenerate solutions in terms of a family of
automorphisms of their associated left rack. In some cases, we show that the
study of reflections for bijective and non-degenerate solutions can be reduced
to those of derived type. Moreover, we extend some results obtained in the
literature for reflections of involutive non-degenerate solutions to more
arbitrary solutions. Besides, we provide ways for defining reflections for
solutions obtained by employing some classical construction techniques of
solutions. Finally, we gather some numerical data on reflections for bijective
non-degenerate solutions associated with skew braces of small order.
