Calculate the Distance Between Fringes on the Screen

What is the distance between the fringes on the screen?

To find the distance between the fringes on the screen, we can use the equation: d = λL / d, where d is the distance between the slits, λ is the wavelength of light, and L is the distance between the slits and the screen. Given that the slits are 7.00 x 10^-2 mm apart and the screen is 60.0 cm away, we need to convert the distances to meters.

Calculating the Distance Between Fringes:

Distance between the slits: d = 7.00 x 10^-2 mm = 7.00 x 10^-5 m
Distance between the slits and the screen: L = 60.0 cm = 0.60 m
Now we can substitute these values into the equation and solve for d:
d = (440 x 10^-9 m) x (0.60 m) / (7.00 x 10^-5 m)
d = 3.77 x 10^-3 m
Therefore, the fringes on the screen are 3.77 x 10^-3 meters apart.
