A diffraction grating has a grating spacing of 2,132 nm. Suppose that you carry out the experiment in the water (refractive index n = 1.
A diffraction grating has a grating spacing of 2,132 nm. Suppose that you carry out the experiment in the water (refractive index n = 1.33). If a light ray of a wavelength 513 nm (in air) is incident perpendicularly upon the grating (immersed in water), what will be the angle in degrees for the first order of diffraction maximum? Express the answer with one decimal place.
