Figure 2 shows apparatus used to determine the number of lines per millimetre on a plane transmission diffraction grating. The laser emits light of wavelength 633 nm. Figure 2 diffraction grating, laser screen Describe an experiment to determine the number of lines per millimetre on the grating. Refer to the equipment in Figure 2 and any other necessary equipment. In your answer you should: state the measurements to be made and the steps taken to ensure that the measurements are taken safely . describe how to process the results . describe how the experiment should be carried out to ensure accuracy.
