The figure below shows two luminous rays, 1 and 2, which are initially in phase and reflected on several glass surfaces. Disregard the slight inclination of the light beam on the right. (a) What is the difference between the distances traveled by the two rays? (b) What should be this difference, in wavelengths, for the rays to be in phase at the end of the process? (c) What is the smallest value of d for the phase difference item (b) to be possible?
