Reflection is a term used in various fields, including physics, psychology, and education. In physics, reflection refers to the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound, and water waves. The law of reflection states that for specular reflection (for example, at a mirror), the angle at which the wave is incident on the surface equals the angle at which it is reflected.
In psychology, reflection is a process that helps individuals gain insight into their professional practice by thinking analytically about any element of it. The insights developed and lessons learned can be applied to maintain good practice and can also lead to developments and improvements for both the professional and their service users.
In education, reflection is a process that helps individuals think about their learning experiences and gain a deeper understanding of the subject matter. It involves thinking critically about what has been learned, how it has been learned, and how it can be applied in the future.
Overall, reflection involves the act of reflecting, as in casting back a light or heat, mirroring, or giving back or showing an image.
