Welcome to the forums! You must make some attempt at the problem yourself before we can help you. What ideas do you have about the experiment? For example how can you select different wavelengths from a lamp and what is it about the LDR that could be used to measure intensity?

i could use a polaroid disc to measure the wavelength
