Reaction time of Light Dependant Resistors

Click For Summary
SUMMARY

The discussion focuses on the reaction time of Light Dependent Resistors (LDRs) when exposed to varying frequencies of light. The user plans to plot reaction time against frequency, specifically using the inverse of frequency (1/frequency) to analyze the data. Key factors include light intensity and frequency, which will be plotted to visualize the relationship. The context of this work is for an Advanced Level Physics project.

PREREQUISITES
  • Understanding of Light Dependent Resistors (LDRs)
  • Knowledge of frequency and light intensity concepts
  • Basic graphing techniques for data visualization
  • Familiarity with Advanced Level Physics principles
NEXT STEPS
  • Research how to plot reaction time vs. frequency using graphing software
  • Learn about the relationship between light intensity and resistance in LDRs
  • Explore data analysis techniques for interpreting experimental results
  • Investigate the principles of photoconductivity in LDRs
USEFUL FOR

This discussion is beneficial for students in Advanced Level Physics, educators teaching about LDRs, and anyone conducting experiments related to light and resistance in electronic components.

I am doing this bit of work on the reaction time of Light dependent 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
