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 a series of colours. This shows that

The Three Major Conflicts 1. Conflict between Newton’s law of motion and Maxwell’s law of electromagnetism: • Newton’s laws---run fast enough‚ you can catch up a beam of light. • Maxwell’s electromagnetism---no matter how hard you chase after a light beam‚ it still retreats from you at light speed. • This conflict gave birth to special theory of relativity • According to special relativity‚ space and time depend on one’s state of motion. 1 2. Conflict between Einstein’s

distribution of weight enabling someone or something to remain upright and steady. This means that when I’m surfing I will be able to maintain balance as I’m riding the wave. There are a variety of exercises you can do to improve your balance such as; Beam walks‚ stork stand test and a wide variety of others. An area which is vital to your balance is your centre of gravity‚ if your centre of gravity is too high to low or outside your body then it will be very hard to surf in a straight line. “Centre

CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Before conducting analysis of crash analysis of a Proton Gen-2 between bumper and rigid wedge‚ information and related journals are reviewed. In this chapter‚ firstly the stress strain diagram is used to start the literature review since it is the basic behavior of a specimen under applied force. Next‚ factors of selecting bumper system components such as the energy absorbing and recyclability are discussed to introduce the properties of a good bumper

CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted‚ reflected off a target and then returned as an echo. Radar makes use of a phenomenon
