An apparatus consists of a laser, a single slit of width a and a shield at distance L onto which the diffraction pattern is projected. It is verified that the central maximum has width W. Some processes (listed below) are performed. Present as an answer the sum of the numbers of the processes that result in a central maximum with 2W width (enter only the number equivalent to your answer):   1 - double the wavelength 2 - Double the laser power 4 - Double the bulkhead distance 8 - halve the wavelength 16 - Double the slit width 32 - HALF DECREASE THE DISTANCE FROM THE BLINDER 64 - HALF DECREASE the slit width 128 - Make the light pass through a material with a refractive index equal to 2 before reaching the slit 256 - Sink the entire apparatus into a liquid with a refractive index equal to 2 512 - Cut laser power in half
