mirror reflection - A convex mirror‚ fish eye mirror or diverging mirror‚ is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards‚ therefore they are not used to focus light. 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. Reflection law - If the reflecting surface is very smooth‚ the reflection of light

from a wide variety of complications and problems. Castagna (1993) showed the myriad of factors affecting seismic amplitudes. According to Sherwood et al (1983) “The simple interface reflection coefficient is only a starting point toward understanding offset-dependent-reflectivity. More often we deal with reflections from layers‚ transition zones‚ or complex layered sequences.’’ A robust data processing scheme for AVO analysis needs to be carefully selected so that noise could be suppressed without

Refraction Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship [pic] From this equation we see that the direction in which the light is bent depends on whether it is going from a slower to a faster medium or vice versa. Index of refraction The index of refraction of

Refraction and Snell’s Law When an ultrasonic wave passes through an interface between two materials at an oblique angle‚ and the materials have different indices of refraction‚ both reflected and refracted waves are produced. This also occurs with light‚ which is why objects seen across an interface appear to be shifted relative to where they really are. For example‚ if you look straight down at an object at the bottom of a glass of water‚ it looks closer than it really is. A good way

This reflection is divided into two parts: the importance of critical reflection and an evaluation of self. The first part will be drawing upon through the appropriate literature‚ and there are four points to prove the importance of critical reflection in personal development. It will be expounded and distinguish Reflection in action and Reflection on action. Then‚ the theory of Single and double loop learning will be introduced. Moreover‚ the reflection also includes the difficulties and challenges
