Reaction time of Light Dependant Resistors

AI Thread Summary
The discussion focuses on the reaction time of Light Dependant Resistors (LDRs) in relation to different frequencies of light. The initial query involves how to effectively graph the reaction time against frequency, with suggestions to consider both frequency and light intensity. The project is for an Advanced Level Physics course, and the participant has decided to plot 1/frequency against reaction time for various wavelengths of light. This approach aims to provide clearer insights into the relationship between frequency and LDR response. The conversation highlights the importance of understanding LDR behavior in experimental physics.

I am doing this bit of work on the reaction time of Light Dependant Resistors (LDR's) with different frequencys of light and i need to be able to get a graph out of it and I am not sure what to do for it. i was thinking of plotting reaction time vs. frequency but apart from making a graph and getting no information out of it i have no idea what to do. I need to have an answer by tomorrow so any help anyone can give would be good.

Nice I did not know about these until this thread. Well you have to factors, frequency and the light intensity hitting the LDR. So you could plot the surface of resistance created by light intensity, and frequency.

I do no know how interesting this is though. What is this for? Robotics class? Physics lab? EE class/project? Capstone?
 
its for Advanced Level Physics. i now know what I am doing I am plotting 1/frequency vs. reaction time at different frequencys of each wavelength of light
 
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 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
