    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...

  • refraction of light in water

    Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon, When light travels from air into water, it slows down, causing it to change direction slightly. This...

    Finding an Angle in a Right Angled Triangle You can find the Angle from Any Two Sides We can find an unknown angle in a right-angled triangle, as long as we know the lengths of two of its sides.  Example A 5ft ladder leans against a wall as shown. What is the angle between the ladder and the wall? (Note: we also solve this on Solving Triangles by Reflection but now we solve it in a more general way.) The answer is to use Sine, Cosine or Tangent! But which one to use? We have a special...

  • Different Angles of Cinderella

    Different Angles of Cinderella Throughout the years, there have been several retellings of Cinderella. Some of the retellings are based on culture, the society at that particular moment and what would grab the audience attention. One of the most common retelling of Cinderella is: The Complete Grimm’s Fairy Tale. There’s also the: Radio Plays for Children. One of the most recent retelling would have to be: A Cinderella Story. All three of the retellings leave the audience with a different interpretation...

  • Speed of Sound

    Phsyics 1 | Speed of Sound | Mastery Experiment | | Lindsay Pickelsimer | 12/3/2010 | | The speed of sound is a traveled distance through a certain amount of time that uses sound waves that spreads through and elastic medium. It usually depends on the temperature to which how fast it travels; speed of sound is increased when temperature increases. Frequency and wave length deals with determining the speed of sound. Speed of sound is inversely proportional...

  • Reflection and Refraction of Light

    determine the angle of the total internal reflection and the index of refraction in the experiment. Theory The theory being experimented in this procedure is that of Willebrord Snell. From his theory we understand that the incident ray, the normal line and the refracted ray all lie on the same plane. We also understand that the relationship is defined in a ratio with the following equation; Which means that the ratio of the sine of the angle of incidence to the sine of the angle of refraction...

    Problem Statement Which food gives the most accurate information about the speed of light? Hypothesis I think that the eggs will give me a more accurate result. Procedures: 1. First, place the (marshmallows, eggs and buttered bread) in the casserole dish, completely covering dish. 2. Next, put the dish of the (marshmallows eggs and buttered bread) in the microwave and cook on low heat. 3. Heat the food (marshmallows, eggs and buttered bread) until it begins to create the hotspots...

  • Chapter One

    atramentous darkness. I see a pinpoint of light, and try to swim toward it. Either I get closer to it, or it gets closer to me, but I can’t tell in the inky darkness. The pinhole expands as it gets closer, and I get pulled toward it. It expands, and suddenly engulfs me in a flash of light. I’m in a perfectly cubical white room, apparently made of marble. I turn around and see the hole I came from. An human-sized black, inky hole. It seems strange in this perfectly white cube. I turn around and start...
