Question

In an experiment using synchroton radiation, a 2.7 x 10^17 Hzbeam of X-rays was incident normal to a mask containing two narrowslits. An interference pattern was recorded a distance 1.1 m awayfrom the mask using a planar detector that was perpendicular to theincident beam. It was found that bright points in this pattern wereseparated by a distance of 0.060 mm. a) What is the wavelength of the X-rays? b) What was the separation of the slits in the mask? Thanks.

Explanation / Answer

                          = c / n                             = 3 x108 m/s / 2.7 x 1017Hz                             = 1.11 nm b) The separation of the slits in the mask                           D= L /                              = 1.11 x 10-9 m * 1.1 m /  0.060 x10-3 m                              = 20.35m = 0.0235 mm
