Question

Suppose a single laser beam is split by mirrors and the two parts of the beam illuminate one slit each of a double slit diffraction experiment. Will this produce the normal two-slit diffraction pattern? Explain Suppose a single laser beam is split by mirrors and the two parts of the beam illuminate one slit each of a double slit diffraction experiment.

Explanation / Answer

The waves interfering must be coherent, i.e., the light has the same frequency and is in the same phase. In Young's experiment, this was achieved by passing the light through the first slit, and thereby diffracting it, producing a coherent wave; this is more typically achieved now by using a laser, and removing the first slit.
