Project: Practical Investigation Aslam Khan‚ Keenan Wong and Jinhyuk Yeh 2013 Aim: To verify Snell’s Law and find the relationship between angle of incidence and the angle of refraction‚ for monochromatic light passing from air into Perspex. Hypothesis: As the angle of incidence increases so will the angle of refraction (directly proportional). Apparatus: * Laser (Monochromatic light) * Rectangular Perspex * Ruler * Pencil * Paper * Protractor * Calculator Method:

the headland from further wave erosion and to ensure the pedestrian pathway stayed open for access to the headland. The wall is ____________metres long and was built in _________. * Processes affected: The main processes affected are wave refraction‚ wave erosion and coastal transportation. The waves refract around the headland and attack the sides of the headland. Because of the sea wall the waves can no longer attack the side of the Otakimiro Headland. This means the waves no longer erode

interface. Furthermore‚ if the interface is between a dielectric and a conductor‚ the phase of the reflected wave is retained‚ otherwise if the interface is between two dielectrics‚ the phase may be retained or inverted‚ depending on the indices of refraction.[citation needed] A mirror provides the most common model for specular light reflection‚ and typically consists of a glass sheet with a

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

the prism‚ it is refracted‚ which in scientific terms means that the light is deviated from its original path. At the point of refraction‚ the white light is separated into the 7 different color components that make up white light: red‚ orange‚ yellow‚ green‚ blue‚ indigo‚ and violet. This separation‚ also know as the dispersion of light‚ occurs because the angle of refraction for each color is different when passing through the transparent

Where did it go? The phenomenon in this situation is called Mirage‚ and it doesn’t happen very often in the nature. Usually this phenomenon is caused by refraction and the vary density of the air. As we learned in the lecture‚ refraction is the light bending when it travels through different index of material. The good example for the refraction is the straw in the glass of water; the straw looks broken in the water. The different index of air and water makes the light bending and it reflects

My variables are the wavelength‚ the glass rectangle‚ lasers‚ angle of incidence and angle of refraction‚ protractor and the distance between the laser and the glass rectangle (beam divergence). My independent variable is the wavelength which I am going to control. My dependent variable is the angle of refraction and angle of incidence. My controlled variable is‚ the glass rectangle‚ the protractor and the lasers‚ also the distance between the laser and

CHAPTER – 10 LIGHT-REFLECTION & REFRACTION Light is a form of energy‚ which enable us to see the object. In this chapter we will study the phenomena of reflection and refraction using the property of light i.e. straight line propagation (Light wave travel from one point to another‚ along a straight line). Reflection of Light When the light is allowed to fall on highly polished surface‚ such as mirror‚ most of the light gets reflected. normal Laws of Reflection 1. 2. The angle

glass using a glass block Principle and Hypothesis The Snell’s Law of Refraction says that – At the boundary between any two given materials the ratio of the sine of the angle of incidence and the angle of refraction is constant for any particular wavelength. The refractive index is determined by the formula – R = Sin i Sin r Where i = angle of incidence of the ray of light r = angle of refraction of the ray of light The refractive index of a medium gives the light

Baldeo Persaud NT1310 Unit 7 Assignment 1: Refraction‚ Reflection and Optics A good example of refraction of light and reflection of light is a rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle‚ which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least
