Below there are three objects a mirror‚ a glass block and a prism‚ it shows and tells you underneath each of the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into

The psychodynamic approach of leadership places emphasis on the relationship between the leaders and the followers‚ plus individual personality characteristics of the leader and the followers. It also‚ emphasised that leaders should encourage followers to gain insight into their own personalities so that they could understand their reactions to the leader and each other. An important assumption in this approach of leadership is that the personality characteristics of individuals are deeply rooted

Crosstalk – The coupling or transfer of unwanted signals from one pair within a cable to another pair. 2. Waveguides – A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH – Fiber-to-the-home 4. Simplex – a. A link that can only carry a signal in one direction. b. A fiber-optic cable

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

The Psychodynamic Approach Key Assumptions: * Assumes that a large part of out mental life operates at an unconscious level * It is assumed that unconscious sexual and aggressive instincts drive behaviour * The personality is made up of the id‚ the ego and the superego‚ which are in constant conflict * Defence mechanisms protect individuals from anxiety producing thoughts * It is assumed that early childhood experiences are important to understanding current behaviour

This experiment seeks to demonstrate the law of reflection - the angle of incidence is equal to the angle of reflection when measured from the normal. Equipment Single slit raybox with power supply Paper Ruler Protractor Sharp Pencil Plane mirror Support for mirror (e.g. wooden block with a groove in‚ or plasticine) Method Draw a line on the paper. Place the mirror on the line and support it so it does not move. Shine the beam from the raybox towards the mirror. Use the pencil

Evaluate Freud’s psychodynamic theory. The godfather of psychology .as he has often been termed. Perhaps he was in his time. Sigmund Freud. Born in Freiberg‚ Morovia‚ to a poor family in the year 1856. His mother was 21 at the time of his birth‚ his father was 20 years her senior. Attitudes towards sex and women were very different at this time. Sex was very much taboo‚ women were treated as second class and children had no rights. Extreme double standards were normal‚ rich men would happily

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
