Photoelectric effect experiment

AI Thread Summary
Systematic and random errors in a photoelectric effect experiment can significantly impact results, particularly when measuring the stopping voltage against photon frequency. Key sources of error include calibration drift, hysteresis, and potential inaccuracies in the photodiode's response to varying light frequencies. Environmental factors, such as temperature fluctuations and electromagnetic interference, may also affect measurements. The experiment's design and apparatus specifics are crucial for identifying additional error sources. Understanding these factors is essential for accurately comparing experimental values of Planck's constant to established ones.

What are the possible systematic/random error that can affect my experimental results?

Unless you give us more details on the goal of the experiment and the nature of the apparatus, the only answer you can get is "lots".
 
Photoelectric effect experiment. Light with different frequencies are shone onto a photodiode therefore a current is produced. We apply a stopping voltage to the current to cease the kinetic energy of electrons. Stopping voltage is plotted against frequency of photons. The graph will cut at a y intercept which we knownas work function. Now we compared our experimental value of Planck's constant to the actual one. Obviously we will get a percentage error. Now I need help with the possible errors

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
