How to slove this question

A laser shines on a pair of vertical slits. The horizontal distance \( L_1 \) between the laser and the ruler is 12.3 m. The distance \( L_2 \) between the laser and the slits is 0.511 m. The distance \( d \) is 0.250 mm.

The diagram shows a laser on the left, projecting light through slits onto a screen on the right. The intensity pattern displayed forms alternating light and dark bands, typically known as a diffraction pattern. To the right of this pattern, a ruler is shown, marked from 0 to 8 centimeters, which measures the spacing of the interference pattern.

The illustration is not to scale. Note that the ruler measures in centimeters.

Calculate the wavelength \( \lambda \) of the light.

\( \lambda = \) [______] nm
