I have to make an experiment that supports the hypothesis that light travels in straight lines except at the point it enters a new medium and i was wondering if somebody could help me out by sending some links for ideas because ive been stuck for a while thanks!
heres the steps
Directions:
1. Design an experiment to support the hypothesis that light travels in straight lines except at the point it enters a new medium.
2. Write experimental procedures using detailed, numbered steps. Do not use paragraphs. Do not use personal pronouns such as you or I.
a. Incorrect: I will pour 10 mL of water into the graduated cylinder. I will transfer the water to a separate container. I will shine the light of the flashlight onto the surface of the water.
b. Correct:
1. Pour 10 mL of water into the graduated cylinder.
2. Transfer the water to a separate container.
3. Shine the light of the flashlight onto the surface of the water.
3. To plan the experimental procedures, consider the following questions:
a. What materials are needed? (If using the PhET simulation, list which tools and mediums will be used.)
b. What safety procedures should be followed? (If using the PhET simulation, safety procedures are unnecessary.)
c. What observations should be made?
i. How will the angle of incidence and the angle of refraction be
measured?
d. What kind of data table is needed? (see example)
4. After writing the procedures and creating a data table, carry out the experiment.
5. Create a lab report with the following sections filled in. Submit a typed copy to the teacher via drop box:
a. Experimental Question: How does a change in medium affect light?
b. Hypothesis:
c. Materials List:
d. Safety Procedures (if necessary):
e. Experimental Procedures:
f. Data Table:
g. Analysis and Conclusions: (Use the data to explain whether the data supports the hypothesis. Discuss any circumstances that may have affected the outcome. Answer the experimental question.)
I need help on this too. My teacher is letting me redo it because the grade I got at first PLS HELp
wow thanks for being soooo helpful 😃
To design an experiment that supports the hypothesis that light travels in straight lines except at the point it enters a new medium, here are some steps and considerations:
1. Start by gathering the materials you will need for the experiment. This could include a flashlight, a container with water, a ruler or protractor for measuring angles, and any other tools you may require.
2. Make sure to follow safety procedures, if necessary. In this case, since we are using a flashlight and water, no specific safety procedures are required.
3. Write down the detailed, numbered steps for the experimental procedure. Make sure to avoid using personal pronouns and write in a clear, concise manner. For example:
a. Pour 10 mL of water into the graduated cylinder.
b. Transfer the water from the graduated cylinder into a separate container.
c. Shine the light from the flashlight onto the surface of the water.
d. Observe and record any changes in the path of the light as it enters the water.
4. Consider what observations should be made during the experiment. In this case, you will need to measure the angle of incidence (the angle at which the light enters the water) and the angle of refraction (the angle at which the light changes direction inside the water). You can use a protractor or ruler to measure these angles.
5. Create a data table to record your measurements. The table should have columns for the angle of incidence and the corresponding angle of refraction. Each row should represent a different trial or measurement.
6. Carry out the experiment by following the procedures you have written. Make sure to record your observations and measurements accurately in the data table.
7. After completing the experiment, analyze the data and draw conclusions. Does the data support the hypothesis that light travels in straight lines except at the point it enters a new medium? Consider any factors that may have influenced the outcome of the experiment and discuss them in your analysis.
8. Finally, create a lab report with the following sections filled in: experimental question, hypothesis, materials list, safety procedures (if necessary), experimental procedures, data table, and analysis and conclusions. Make sure to type your lab report and submit it to your teacher via the designated method.
For additional ideas and resources, you can search online for experiments related to light refraction or check educational websites and science experiment databases. These resources can provide you with different setups and variations to support your hypothesis.
I don't know how useful this will be but here it is.

Also check out the directions, especially 2b 3. That should be a good starting point for an experiment. Good luck.
