Suppose the interference pattern shown in the figure below is produced by monochromatic light passing through a diffraction grating, that has 100 lines/mm, and onto a screen 1.75 m away. What is the wavelength of light if the distance between the dashed lines is 48.8 cm?

Step 1

Consider the distance between the slits of the diffraction grating be *d*, the wavelength of the light be *λ*, the distance between the constructive maxima, that is the...
