How do this plan about waves for physics?

Special lamps may be purchased to help plants grow indoor.These lamps produce light with wavelengths comparable to natural sunlight. A manufacturer wishes to check these lamps by measuring the output of the lamp at different wavelengths. You are required to design a laboratory experiment using a light dependent resistor(LDR) to investigate how the intensity of light emitted by a lamp varies with wavelength. You should draw a diagram of the arrangement of your apparatus,and in your account you should pay particular attention to a)the procedure to be followed b)how the wavelength of the light falling on the LDR is determined c)how a measure of the intensity can be obtained from the LDR d)the range and precision of any instruments that would be used e)the factors that would need to be controlled to ensure that it is a valid test f)any safety precautions you would take when carrying out the investigation thank you see my Question,it the greatest if you help me.

1. do your own homework
2. im stuck too! in the potential divider circuit, what do i use the variable resistor for????????????? i dont get it! i need help quick ive only got tomorrow morning left
3. this is our planning exercise for college. i think you have to use the LDR and vary the light source. to work out the wavelength of the light a spectrometer needs to be used
