how the intensity of light emitted by lamps varies with wavelength?

i need to know; The procedure to be followed: How the wavelength of the light falling on the LDR is determined: How a measure of the intensity can be determined from the LDR: The range of precision of any instruments that would be used: The factors that would need to be controlled to ensure that it is a valid test: Any safety precautions you would take when carrying out the investigation: Particular features of the design that would ensure the accuracy and reliability of your results.

1. Is this what you mean? "Light-dependent resistor (LDR) - SensorWiki A light-dependent resistor, alternatively called an LDR, photoresistor, photoconductor, or photocell, is a variable resistor whose value decreases with" Would have been nice to define your acronyms. Presumably the wave length is measured with an expensive tool or by color matching. Since it is a resistor, the more light, the lower the resistance. Information about its spectral response is also needed. Safety: how intense is the light.
