Refraction is the change in direction of a wave due to a change in its speed. This is most commonly observed when a wave passes from one medium to another. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth.
Reflection is 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 says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.
In acoustics, reflection causes echoes and is used in sonar. In geology, it is important in the study of seismic waves. Reflection is observed with surface waves in bodies of water. Reflection is observed with many types of electromagnetic wave, besides visible light. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors.
Self Reflection
Introspection is the self-observation and reporting of conscious inner thoughts, desires and sensations. It is a conscious mental and usually purposive process relying on thinking, reasoning, and examining one's own thoughts, feelings, and, in more spiritual cases, one's soul. It can also be called contemplation of one's self, and is contrasted with extrospection, the observation of things external to one's self. Introspection may be used synonymously with self-reflection and used in a similar way.
Echo
One day when Narcissus was out hunting stags, Echo stealthily followed the handsome youth through the woods, longing to address him but unable to speak first. When Narcissus finally heard footsteps and shouted "Who's there?", Echo answered "Who's there?" And so it went, until finally Echo showed herself and rushed to embrace the lovely youth. He pulled away from the nymph and vainly told her to leave him alone. Narcissus left Echo heartbroken and she spent the rest of her life in lonely glens, pining away for the love she never knew, until only her voice remained.
My reflection in the form of shadow in the background while holding a narcissus:
Philosophy is the study of general and fundamental problems concerning subjects such as existence, knowledge, values, reason, mind, and language.
In the more informal sense, a philosophy is an attitude to life or way or principle of living whose focus is on resolving the most basic existential questions about the human condition. Philosophy is distinguished from other ways of addressing fundamental questions (such as mysticism or mythology) by its critical, generally systematic approach and its reliance on reasoned argument.Philosophy comes from the Greek φιλοσοφία [philosophia], which literally translates to "love of wisdom".
Different Kinds of Waves:

Transverse Waves...
and then there are
Tides...and so the research continues...
