Include your name, instructor's name, date, and name of lab.




Objective(s):

In your own words, what was the purpose of this lab?

The purpose is to see how light bends in different circumstances.


Hypothesis:

In this section, please include the if/then statement you developed during your lab activity. This statement reflects your predicted outcome for the experiment.

If I project light rays through (choose one: air, water, glass), then they will refract, or bend, the most.




Procedure:

Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Test variable (independent variable):
Outcome variable (dependent variable):




Select Intro to begin.

Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen. Select the More Tools icon at the bottom of the lab interactive and be sure to select the Normal and Angles boxes. Do Not move the laser light.

You will test all three materials in the bottom, blue half of the screen: air, water, and glass. Remember, do not move the laser light.

Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen




Data:

Record the data from each trial in the data chart below. Be sure to fill in the chart completely.

Material

Interactions
List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen.

Evidence
Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.

Trial One

Air on top

Laser keeps going straight

Bottom angle: 45

Bottom index of refraction:1.00

Air on bottom

The light is reflected

Trial Two

Air on top

The light is refracted

Bottom angle:31

Bottom index of refraction:1.33

Water on bottom

The reflected ray is dimmer

Trial Three

Air on top

The light is reflected

Bottom angle:29

Bottom index of refraction:1.50

Glass on bottom

The light is refracted

The reflected ray is dimmer




Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

Did your data support your hypothesis? Use evidence to explain.

Which material refracted the light rays the most: air, water, or glass?

Which material refracted the light rays the least: air, water, or glass?

How does density affect refraction?

Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

Explain where you observe reflection, refraction, and absorption of light in your everyday activities.

Answer 1

The lab results confirmed the hypothesis that glass refracts light the most, followed by water, with air refracting the least, due to their respective indices of refraction. Daily observations of light interaction include reflection in mirrors, refraction in glasses, and absorption by dark surfaces. Diamonds refract light intensely due to their high density, contributing to their sparkle.

Step-by-step explanation:

In conclusion, the lab results indicate that different materials refract light to varying degrees due to their different indices of refraction. Based on the observations and data collected, the hypothesis is supported by the evidence that light rays refract the most when passing through glass with an index of refraction of 1.50, and the least through air with an index of refraction of 1.00. As the light moves from air into water and glass, it bends towards the normal line due to the increase in optical density. With glass being the most dense in this experiment it caused the greatest bending of light, as seen from the data with an angle of refraction of 29 degrees. In our daily lives, reflection, refraction, and absorption can be observed in many instances such as mirrors reflecting light, lenses bending light in glasses, and dark surfaces absorbing light. Diamonds, due to their high density and high index of refraction, would significantly refract light, resulting in the distinctive sparkle they are known for.

Answer 2

Conclusion:

The purpose of this lab was to observe how light rays interact as they pass from one material to another. The hypothesis stated that if light rays are projected through a material, they will refract the most. The data collected in this lab supports the hypothesis. When light rays were projected through air onto the different materials, they either refracted or reflected. The angle of refraction was measured for each material and it was found that the angle decreased as the index of refraction increased.

Water refracted the light rays the most while air refracted the least. The density of a material affects refraction because it changes the speed at which light travels through the material. A more dense material causes light to travel slower and bend more, leading to greater refraction. If light was projected through a diamond, it would refract significantly due to the high density of diamond.

Reflection, refraction, and absorption of light can be observed in many everyday activities. Reflection can be seen in mirrors, windows, and other reflective surfaces. Refraction can be observed when light passes through a lens or prism, causing the light to bend and create a spectrum of colors. Absorption can be seen when certain colors of light are absorbed by objects, making them appear a different color.
