SUMMARY
This discussion focuses on designing a laboratory experiment using a Light Dependent Resistor (LDR) to measure light intensity as it varies with wavelength. The experiment involves using diffraction gratings to separate light into different wavelengths. The key challenge presented is obtaining a quantitative measure of light intensity from the LDR. Understanding the specifications of the LDR is crucial for accurate measurements.
