Answer:
To determine the distance from the slits to the screen when shining a laser pointer (λ=652nm) through a pair of slits separated by 250 μm, we can use the formula d = λL / w, where d is the distance from the slits to the screen, λ is the wavelength of the laser pointer, L is the distance between the slits and the screen, and w is the separation between the slits.
Using the given values, we have:
d = (652 nm) x (L) / (250 μm)
To solve for d, we need to convert the units to be consistent. Converting 652 nm to μm, we get 0.652 μm. Substituting the values, we get:
d = (0.652 μm) x (L) / (250 μm)
Simplifying, we get:
d = 2.608 L / 1000
Therefore, the distance from the slits to the screen should be at least 2.608 times the distance between the slits and the screen. Based on the search results, the distance between the screen and the slits can vary depending on the experiment and the equipment used. However, a distance of at least 1.5 meters (4.9 feet) [2] or 1 mm[1][3] has been used in some experiments.
