**Interference Pattern Problem**Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of a single wavelength. It then falls on two slits separated by a distance of 0.470 mm. In the resulting interference pattern on a screen, which is a distance of 2.23 m away, adjacent bright fringes have a separation of 2.79 mm.**Part A***Question: What is the wavelength?*The problem involves calculating the wavelength (λ) based on the given parameters using the double-slit interference formula: \[ \lambda = \frac{xd}{L} \]Where:- \( x \) is the fringe separation: 2.79 mm- \( d \) is the slit separation: 0.470 mm- \( L \) is the distance to the screen: 2.23 m\[ \lambda = \](*Answer box in meters with submission button*) Buttons for text formatting and math symbols are provided to help with input. **Request Answer** - Option to request the solution if needed.
