266 Appendix 2 Construction The inside of the tube should be sprayed matt black to prevent internal reflections. One end is covered with kitchen aluminium foil in which a slit is cut with a razor blade, and the other end is similarly covered and a 5 mm hole drilled in the foil. A piece of grating replica is stuck over the hole, so that the slit and the grating lines are parallel. The direct slit will be seen through the grating with the first order spectrum on one side.

Apparatus, materials, and reagents 5 Heat of combustion apparatus (Topic 7) A suitable apparatus, devised by R. J. Sutcliffe, for determining the heat of combustion of alcohols can be made by mounting a copper tube containing copper turnings inside a glass tube containing water, as shown in figure A.5. 6 Bragg phase difference simulator (Topic 8) The apparatus is shown in figures A.6, A.7, A.8, and A.9.
