Properties of Light Lab Report Instructions: In the Properties of Light—Bending Light Lab you will explore how light rays interact as they pass from one material, or medium, to another. Record your observations in the lab report below. You will submit your completed report. Name and Title: Include your name, instructor's name, date, and name of lab. Cameron Brandl 8/21/2023 Properties of Light Lab Report Objective(s): In your own words, what was the purpose of this lab? I will find out what happens if light refracts, or bends as it passes from one material into another. 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
, water or glass then they it will refract most of it but if I do it with air than it stays the same. 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): 1.
Select Intro
to begin. 2.
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. 3.
You will test all three materials in the bottom, blue half of the screen: air, water, and glass.
4.
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
As the laser goes through air, it stays at a 45-degree angle. Angle:45.0 Index of refraction:1.000 Air on bottom
The 45-degree angle is kept from the top of the screen. Trial Two
Air on top
As the laser goes to the halfway point on the screen, it stays at a 45-degree angle then it bounces back at a 45-degree angle but to the right. Angle:32.0 Index of refraction:1.333 Water on bottom The angle changes from 45 to 32 Degree angle. Trial Three
Air on top
As the laser goes to the halfway point on the screen, it stays at a 45-degree angle then it bounces back at a 45-degree angle but to the right. Angle: 28.1 Index of refraction:1.500 Glass on
bottom
The angle changes from a 45 to 28.1-degree angle. Conclusion: Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
1.
Did your data support your hypothesis? Use evidence to explain. My hypothesis was right because all the evidence is correct with the hypothesis. 2.
Which material refracted the light rays the most: air, water, or glass? The material that refracted the light raised the most is glass because it's the most. density material, I would say. But it is still see through. So light rays go through it, but it also bounces off. 3.
Which material refracted the light rays the least: air, water, or glass? The material that reflected the light raised the least is air because it is see through and not touchable Also, it's not as dense. 4.
How does density affect refraction? Density effects refraction. Because the harder something is. The more it bounces off, I would assume. 5.
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond. What would happen if a light ray was projected to a diamond Well, it would happen like glass, but since it is denser, the light ray will change more like a. different angle. But since still see through, I would assume that it also goes through it and gives off A bounce effect. 6.
Explain where you observe reflection, refraction, and absorption of light in your everyday activities Explain where observation reflection and absorption of light in your everyday activities well. It would be a mirror because you must see yourself which light has to hit your eyes, which is reflection. And it also must absorb that information. I would assume.
