In a double slit experiment, the distance between the slits is 5.0 mm and the slits are 1.0m from the screen. Two interference patterns can be seen on the screen one due to light with wavelength 480nm, and the other due to light with wavelength 600nm. What is the separation on the screen between the third order bright fringes of the two intergerence patterns?

Explanation

To solve the problem of finding the separation on the screen between the third-order bright fringes of two interference patterns in a double slit experiment, we will follow these steps:

### Step 1: Understand the given data
- Distance between the slits (d) = 5.0 mm = 5.0 × 10⁻³ m
- Distance from the slits to the screen (D) = 1.0 m
- Wavelength of light 1 (λ₁) = 480 nm = 480 × 10⁻⁹ m
- Wavelength of light 2 (λ₂) = 600 nm = 600 × 10⁻⁹ m
