An apparatus is formed by 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 1- Doubles the wavelength 2- Double the laser power 4- Fold the bulkhead distance 8 - Halve the wavelength 16 - Double the slit width 32- Decrease by half the distance from the bulkhead 64 - Decrease the slit width by half 128 - Making the light pass through a material with a refractive index equal to 2 before reaching the slit 256 - Sink the entire apparatus in a liquid with a refractive index equal to 2 512 - Cut laser power in half

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
1- Doubles the wavelength
2- Double the laser power
4- Fold the bulkhead distance
8 - Halve the wavelength
16 - Double the slit width
32- Decrease by half the distance from the bulkhead
64 - Decrease the slit width by half
128 - Making the light pass through a material with a refractive index equal to 2 before reaching the slit
256 - Sink the entire apparatus in a liquid with a refractive index equal to 2
512 - Cut laser power in half
Given that:
Slit width=a
Slit to screen distance=L
Width of central maxima=W
To determine:
