Find a picture from a media source (movies, TV, comics, video games, etc.) that contains either something that is producing sound waves or something that is producing light waves with clear regions in the image where reflection and refraction of those waves occur. Place the picture in the following diagram template and reference the image using APA format.
Note: Please ignore any science fiction, fantasy, or magic when determining where the notations go. Use only your physical science knowledge from the course notes. If anything is unclear in the image and you feel further explanation is needed, you may use the boxes in the key to clarify.
Open your diagram template and do the following:
1. Move and resize the red circle so that it is around an object in your diagram that is producing sound or light. Label the circled object in the key.
2. Move and resize the black waves so that they are indicating the direction the light or sound wave is acting. Remember, these are a visual representation of these waves in your image. You may also copy and paste these waves to produce more if needed.
3. Move, rotate, and resize the green double arrow so that it indicates how wavelength would be measured within this wave. Be sure to reference your course notes for the exact definition of how wavelength is measured, as it is NOT the entire length of the black waves.
4. Move the orange dot to a place on the diagram where reflection of the light or sound wave may occur.
5. Move the purple dot to a place on the diagram where refraction of the light or sound wave may occur.
6. Save your diagram as a PDF 

I need this answered short and to the point not confusing please.

Instructions:
Review the page M2 How to Write a Lab Report and any feedback from your previous lab reports on formatting. Download and complete the M3.5 Laboratory Report 7 Worksheet.
Compose a laboratory report labeled M3.5 Laboratory Report 7 and your name. Remember the key expectations:
The report must be accurate and clean.
Add the calculations in your report using the “Formulas” function, or complete them on a paper, neatly and clearly, and insert a picture of the calculations in your lab report.
Your data must be organized in a table using Excel and then inserted by copy and paste into the report you created.
Use Vernier Graphical Analysis for the graphing. Then, insert the graph into your report. (if applicable)
Upload your Lab Report as a complete file, including all calculations, data tables, and graphs. (if required)
Scan and save your worksheet, together with your handwritten or typed solutions to each problem, as a .doc, .docx, .pdf, or .rtf file.

Topic:
Investigate the theoretical background or advanced techniques/applications of IR spectroscopy, or other forms of spectroscopy such as UV/vis. This is a very broad topic, so you should specialize towards an application within your field interest, i.e. certain organic compounds, astronomical observations, stellar/exoplanet search, etc..
Ps: we have the paper proposal, so the research paper should use and be based on the paper proposal
I have 2 source provided,  but I would need 1 more source to make the paper more professional

Strange topic for an Physics 100 class but it is very wide open.
Topic is Social Media and its effects on society.
Must have 5 sources, no Wikipedia
Will be a standard speaking presantation with speaker.
Just ideas,
a. Influence of social media on people’s mindset
b. Role of social media in spreading misinformation
c. Role of social media in spreading toxic content

Lab 1 Background and Instructions
Lab 1: Electric Charge, Electric Field and Electric potential
This is an individual lab, and it is based on concepts from the first two modules in this course: ” Electric Charge and Electric Field” and “Electric Potential and Electric Potential Energy”.
You are advised to complete the lab after you have completed the summary sheet for Chapter 19: you will need to be familiar with how to calculate Electric Potential and Potential Energy.
In this lab you will use Phet Interactive Simulations to study the electric field and the electric potential in the space surrounding one or more point charges.
You will use the “Charges and Fields” PhET simulation which you can open by clicking on the link bellow:
https://phet.colorado.edu/en/simulation/charges-and-fields
Just hit the polay button and it will run the software.

Directions: 1. Double Click on the Lab to open
2. On the right hand panel Check the following boxes: Displacement, Natural Length, , Movable line, and Equilibrium.
3. Make the Damping lots
4. On the box to the left of the spring, slide the blue rectangle to the left so that the reading is 50 g also move the blue rectangle box on Spring constant to two divisions from Large.
5.Below the right hand panel there is a yellow colored ruler, Click on it and drag it to the spring so that it is vertical . Make sure the zero reading on the ruler is aligned with the tip of the spring.
6. Click on the Orange colored cylinder reading 50 grams and drag it to the tip of the spring so that it hangs on the spring.
7. The Spring will stretch. The extended length is the reading on the meter rule corresponding to the point the end of the spring is at on the rule. Record this reading .
8. Increase the mass of the orange cylinder to 70g and note the extension. ( The masses should be 50,70,90,110,130,150,170,190,210,230,250,270,300)
9. Repeat this until you reach 300g.
10. Remove the orange cylinder and hang the Blue cylinder and record the extension. Also do the same to the red cylinder.
Make a table on paper to resemble the one below
Record the rsults obtained below . This and anyother below are required to be posted into the assignments.
This table should be pasted in your submission
Extension due to Blue Cylinder ＝ Extension due to red cylinder ＝
1. Plot the graph of the mass in Kilograms (Vertical) versus the the extension in Meters (Horizontal)
2. Find the slope of the graph 3. Find the equation of the straight line obtained. The equation should be n Mass ＝ slope of straight line multiplied by extension + a constant if any.
4. Using the equation of the line what are the masses of the Blue and red cylinders.
