Final answer:
The distance between the central maximum and the third intensity minimum in a double slit experiment can be found using the formula: d = (m * λ * L) / (2 * d). Let's assume a value for λ and L and calculate the distance d.
Step-by-step explanation:
The distance between the central maximum and the third intensity minimum in a double slit experiment can be found using the formula:
d = (m * λ * L) / (2 * d)
where d is the distance between the double slits, m is the order of the minimum (in this case, 3), λ is the wavelength of light, and L is the distance between the double slits and the screen.
Let's assume a value for λ and L and calculate the distance d.
