Yellow light $(\backslash$lambda $=580$ nm$)$ is incident upon a diffraction grating which has $700$ lines per millimeter. The first bright spot is found to be $68$ cm away from the center. If you,

instead, shine blue light $(\backslash$lambda $=460$ nm$)$ on this grating, where will the first bright spot be located? Please include calculations including the distance and angle of the blue light.
