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

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

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

Good relationship can enhance our sense of identity. sharing special relationships with people is one of the most rewarding and elevating moments of our lives. We categorize ourselves in terms of other people and groups. Evolution has taught us that it is beneficial to live in tribes‚ where we can share out the work of daily survival. When asked about yourself‚ you may well describe yourself in terms of your work and family relationship. Although we defined ourselves by our membership of groups‚

‘Interpreter of Maladies’ explores how one culture adapts to living with another.’ Discuss. In Jhumpa Lahiri’s short story collection ‘Interpreter of Maladies’‚ the writer silhouetted the adaption of one culture to live within another in the form of allowing differences to exist and reaching a compromise. Lahiri drew the readers into the witness of different people battling with the obstacles they encounter. While some people like Mrs Sens‚ fell to the abysm of culture-displacement because of

potential. One’s identity is formed and influenced by the groups one belongs to. Humans are by nature sociable beings that must learn to cooperate for peaceful existence to occur but are also individual personalities who seek their own self fulfilment. Belonging to groups; family‚ social or environmental groups‚ can have immeasurable benefits. But while groups do provide one with a sense of identity‚ security and protection it can however result in sacrifices to selfhood and can entail certain inevitable
