Double-slit setup illuminated by red and violet laser light.
Double-slit setup illuminated by red and violet laser light.
A red laser with wavelength \(\lambda_R = 600 \text{ nm}\) and a violet laser with wavelength \(\lambda_V = 400 \text{ nm}\) simultaneously shine through a double slit onto a screen located a distance \(L\) away. On the screen, the second-order bright fringe for the violet light is located at a distance \(y_V\) from the central bright fringe. Assuming the small-angle approximation holds, what is the distance from the central bright fringe to the second-order bright fringe for the red light?
