(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

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
