How were your results? Need Help With Physics? The x and y intercepts of our trendline produced the inverse of our theoretical focal length. The slope of the line for the water graph showed that our experimental value for the index of refraction was 1.3672, while the actual value is 1.33. this contact form
What are potential sources of error for this lab? At that point, there was no image. It might contain other materials (impurities) due to a manufacturing error or manufacturing limitations. 2. This was the experiment: Part A) take a glass prism, and shine a single ray of light at it with a ray box, from specific angle of incdence (10 degrees -
I was also able to find out that when the angle increases from 90 towards 180, the angle of polarization is directly proportional to intensity. Part B) same as part a. Yes No Sorry, something has gone wrong. Physics??
Answer in units of m/s.? This is all evidence that proves the lenses equation to be true. This is opposite the rule for convex mirrors. 3. Snell Law Experiment Report Our experimental results are very near the theoretical values, which means our values for n are very precise. 2.
We know this because of our reading done on the Physics Classroom. We also had to guess whether or not the two lines were the same brightness. Our two values were relatively close to one another and had a percent difference of 0.78% and the average of the two was 49.31 cm. https://answers.yahoo.com/question/index?qid=20110504150116AAg025X This would lead you to the wrong calculation of the constant velocity in the horizontal direction and this constant velocity is one of the components in the equation for determining the
After showing how the Snell's law equation could be seen in our graph, it was evident that we had collected today that would prove our hypothesis correct. Snell Law Experiment Conclusion When an image is created during this part, it will be real and inverted. We know this to be true after reading lessons from the Physics Classroom and work done in class. I've already written about the thickness of the light ray, and the accuracy of the polar graph.
Get it on the web or iPad! Like a convex mirror, concave lenses always produce virtual, reduced, and upright images. Index Of Refraction Lab Sources Of Error This was because when the beam of light exited, it spread out and was not a fine, focused beam, which made it tougher to get the perfect mark. Sources Of Error In Reflection And Refraction Lab Air resistance could slightly effect horizontal displacement of the marble.
Calculate the speed of an 6.0 × 104 kg airliner with a kinetic energy of 1.4 × 109 J. weblink Expand» Details Details Existing questions More Tell us some more Upload in Progress Upload failed. Then, we marked the point where the beam of light escaped from the other side of the prism and drew a line with a ruler from where the light entered, to Our experimental value for acrylic is 1.5202 and the theoretical value is 1.49, our percent error for water is 2.03%. Refractive Index Of Glass Experiment Errors

Answer Questions Calculate the speed of an 6.0 × 104 kg airliner with a kinetic energy of 1.4 × 109 J. navigate here For 75% transmittance our error was 0.67%, 50% was 8.14%, and 25% was 21.3%.
Discussion Questions: How do polarizing filters work? Snell's Law Using the value of n determined for the acrylic block, find the speed of light in the prism. 4. The system returned: (22) Invalid argument The remote host or network may be down.
i need as much help as i can get thank you Add your answer Source Submit Cancel Report Abuse I think this question violates the Community Guidelines Chat or rant, adult Please try the request again. Next, position the convex lens between the light source (the object) and the screen. Overall, in the future, I would change the lab by using a stronger beam of light.
Why there was no image for when the object was placed at the focal point can be proven mathematically using our equation. help on how to format text Help · About · Blog · Pricing · Privacy · Terms · Support · Upgrade Contributions to https://honorsphysicsrocks.wikispaces.com/ are licensed under a Creative Commons Attribution This shows that we almost validated the law perfectly. http://phabletkeyboards.com/sources-of/sources-of-error-when-using-a-spectrophotometer.php The system returned: (22) Invalid argument The remote host or network may be down.
Like a concave mirror, convex lenses will produce either real or virtual images depending on object distance. Our goal was to obtain about 10 data points. No. Our rationale is Snell's Law: n1 is the index of refraction for air which is 1.0 so: Following the equation for a line, y = mx + b, it is clear
We had relatively small error everywhere. Explain your results for trials 4 and 5 in Part B. This is relevant in real life through everyday objects, such as windows and sun glasses. Before you adjust the lens or screen, you must measure the size of the arrow and record it as the object size.
