Light Effects Refraction‚ reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would

Examining the Refraction of Light in Prisms Questions 1. What is the relationship between the angle of incidence and the angle of refraction? The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling though perspex and the normal). The graph of the plotted angles of incidence against the angles of refraction is not a straight line and therefore demonstrates

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

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
