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.

Work on the two questions  I will provide an example of what my professor wants it done
1. A
monochromatic light source used in a diffraction experiment has a wavelength of
4.60 * 10^-7 m. What is the energy of a photon of this light?
2. How much greater is the energy of a photon of
ultraviolet radiation ( λ= 3.00 X 10^-7 m) than the energy of an average photon
of sunlight (λ = 5.60 X 10^-7 m)?
Example
1. An
incident light ray strikes a mirror with an angle of 30° to the surface of the
mirror. What is the angle of the reflected ray?
Step 1: List of the variables.
Incident angle (θi) = 30°
Reflected angle (θr) =?
Step 2: Relevant equation.
θi = θr
Step 3: Solving the equation for the unknown variable (Reflected angle, θr)
Since θi = θr, no additional solving is
needed.
Step 4: No need for unit conversion as angles are dimensionless.
Step 5: Substituting the known values into the equation:
θr = θi
θr = 30°
Step 6: Performing the mathematical operation:
No mathematical operations are needed in this
case.
Step 7: The answer is reasonable since the angle of reflection is equal to the
angle of incidence, which is a characteristic of the law of reflection.
Step 8:
put your answer in a box
