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

(a) Sensory organs are possessed by human and all animals. (b) Sensory organs allow the body to respond to the stimuli surroundings. Stimuli from the surroundings. Stimuli are changes that happen in the environment. (c) Sensory organs have receptors that receive the stimuli and then‚ send them as impulses to the

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

How is someone born already knowing certain things? Let’s take a look at some of these questions by first looking at a man named Socrates. Point 1- Law of opposites: Socrates believed that human beings have lived prior lives so to try to explain and validate the point on living prior lives he used the law

describing the occurrences Caesar endured during his time of death. Some of the main points the movie stated was that he was a master a manipulating people‚ he had epilepsy‚ he screamed out “kill me now‚ I won’t resist!”‚ and that he was sick with diarrhea and drowsiness. Most of these actions‚ the investigator thought‚ were due to the epilepsy. I believe it‚ but I also believe all of this was what made Caesar want to commit suicide. But in my mind‚ he didn’t commit suicide‚ but instead asked others to
