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

Mary Fenning Lab 12 Reflection‚ Refraction‚ & Lenses Introduction The purpose of is lab is to observe ray models of light and how light refracts and reflects through a straight line and Snell’s Law. Procedures Setup and materials: Part IV: Procedure: Using the slit plate observe the rays on the viewing screen set Rotate the slit plate until the slits are horizontal. Record what image looks like at the different angles Trace the rays onto a white piece of paper and extend the lines

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

When looking at the surface of the water from different angles‚ I was able to see a magnified penny as well as multiple pennies. This is once again due to the reflection and reflection of light. The bottom penny is reflected up by the light above‚ while the two additional pennies I viewed were due to refraction on the sides of the glass. This is due to the light entering the different mediums and slowing down. The angle

While experimenting with the speed of light‚ I noticed that the light being refracted was slower when it shined through a denser medium. For example when the higher medium was water and we were comparing it to air‚ the speed of the light being refracted was 0.75 c. If we were to switch the medium to glass‚ which is more dense than water‚ the speed of the light decreased to 0.67 c. For two of the mediums they were both placed at the same angle when we started shining the light and as the outcome

The green line represents the original beam of light that is incoming from the laser. When light passes through the water tub‚ it undergoes both reflection from the surface and refraction. The yellow arrowed line shows the beam of light that is reflected and the red arrowed line shows the pathway of the light beam after it has undergone refraction. It can be noticed that there is a lateral displacement

How does the Wavelength affect the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the

Investigating Snells Law Investigating Snell’s Law Research Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where
