refractive index and the ray should hit the center of the glass circle‚ so to check that the ray hits the center of the glass circle‚ we placed a wood block at the angle of reflection to see if the angle of reflection is the same as the angle of incidence‚ because we know that the angle of incidence is equal to the angle of reflection. Another thing which makes it easier to hit the center of the glass circle is by placing a paper on the flat side of the circle and see if the ray hits the center of the

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

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

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

mirror reflection - A convex mirror‚ fish eye mirror or diverging mirror‚ is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards‚ therefore they are not used to focus light. Reflection - is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Reflection law - If the reflecting surface is very smooth‚ the reflection of light

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
