1.	Methods in measuring lenghts?
Answer» Answer: Length measurement. Length measurement is implemented in practice in many ways. The most COMMONLY used approaches are the transit-time methods and the interferometer methods based UPON the speed of LIGHT. For objects such as crystals and diffraction GRATINGS, diffraction is used with X-rays and electron beams.
