1. ### I Relationship between the Different Frequency vs Decibel Graph Peaks

In the popular answer for the coin-mass question of Physics Stack Exchange, I am wondering what are the correlation between the first red peak at around 9kHz and the second red peak at 16kHz. I first thought that they are consecutive harmonics but there was no way of proving it as I do not know...
2. ### MATLAB Numerical approximation of the area under curve

I am very new too Matlab and how it all works but I am having trouble understanding at what axis the numerical integration is occurring from on the graph that I plotted. So I am currently doing an experiment in gamma ray spectroscopy and due to issue with the software we found it hard to...
3. ### I Measurement of the mean value of the number of photons?

Hi everyone, I do experiment in field of quantum optics and I want to calculate the mean of the number of photons (MNP). In the most of papers, MNP can be calculated by using average power which is measured by power meter. But my power meter is defective. For now, I have only the avalanche...
4. ### Parallel Axis Theorem Experiment

Homework Statement I am currently working on a physics experiment to confirm the parallel axis theorem. To do this, I have the following setup: In this experiment I change the distance between the centre of the rotating disc and the central axis. I record the time for 5 complete rotations...
5. ### Gyroscope Experiment Homework: Find Centre of Gravity & Nutation Effects

Homework Statement Ok so in my lab we have been given a set-up as shown below Minus the horse shoe dector on the right hand side. During this set-up up we need to find the point where the balance point and centre of gravity are equal (as I understand) here is exactly what my script say...

### Experimental thermodynamics properties

Hello everybody, I am using an equation of state to calculate the thermodynamical properties of a material. I have a problem which is the ideal part of the equation. Actually, I cannot be sure that the ideal contribution in my equation is the really ideal contribution, so I decided to calculate...
7. ### Using multiple mirrors in Michelson Interferometer

The number of mirrors typically used in Michelson Interferometer is 2. I am looking up the respective Wikipedia article and MIT's youtube video. I am wondering, for the sake of one of my experiment, whether more than 2 mirrors can be used in the interferometer? I require the traversing mirror...
8. ### B The Latest Higgs Boson Mass Measurements

It is summer conference season for physicists and one of the highlights this time around is the first set of new Large Hadron Collider Run-2 measurements of the Higgs boson mass. The Status Quo At the end of Run-1 at the Large Hadron Collider (LHC), the combined estimate of the Higgs boson...
9. ### Experimental preparation for IPHO?

Hello everyone I am a student in the high school and I join the physics Olympiad's team. I am actually good in theoretical physics but on the other hand I can't do any experiment because I'm very bad in the experimental area. I don't know what I have to do and how, in the first round to choose...
10. ### I Determining Appropriate Focal Length

So I'm working on a project where we're deciding a new lens to use for our laser diode. I need to determine the appropriate focal length based on the equation: 1/ƒ = 1/μ + 1/σ where ƒ is our focal length, μ is the distance from the lens to image and σ is distance from lens to object. For the...
11. ### Schools What is the best for an experimental particle physicist?

I'm interested to become an experimental physicist particularly in particle physics. I have the chance to pursue a double degree. what is the best choice that will help me more in my future career.- a double degree in physics and computer science or a double degree in physics and material...
12. ### How to find Kepler's law from Newton's laws

We were asked to do an experiment where we had to prove the equation: T2=(4π2m)/Mgr Where M is the mass of the mass stack in kg (0.3kg), m is the mass of the rubber bung in kg (0.0226kg), T is the time taken for one rotation in seconds, r is the horizontal radius of rotation in meters, and g is...
13. ### How to Determine the Concentration of I2 in a Solution Experimentally?

Hi, We have been supplied an Iodine (I2) solution 0.005M.for an experiment but we are supposed to standardize the iodine solution (which i guess means that to find the exact concentration of the I2 solution) My idea is that we should do a titaration,but I don't know how to or what to do. So if...
14. ### Does Channel-Based Liquid Cooling Outperform Fin-Based in Heat Reduction?

I am not sure if this is the correct place to post, but here goes. I have to do an experiment on liquid cooling, using 2 types of liquid cooling blocks, one fin based, one channel based. The liquid used is water, and the pumping system is the same. The cooling blocks are attached to a...
15. ### Recreating the Millikan Experiment: Analysis and Error Considerations

We've had to recreate the famous Millikan oil drop experiment in our labs and taken values of the velocities of oil drops under the influence of gravity and charged capacitor plates and the balancing voltage required to stop the droplet from moving up or down. We took 120 results and they...
16. ### Setting Up a Pendulum Experiment to Test a Program

A while back i posted a thread on a program designed to analyze and predict the motion of a pendulum. Now i need to set up an experiment to test the program. For those who don't remember/didn't see the last thread, the program can predict the motion of the pendulum at any time in its swing...
