$The intensity of light with wavelength λtraveling through a diffraction grating with N slits at an angle θis given by I(θ)=N^2 sin^2 k / k^2, where k=(πN d sinθ) / λand d is the distance between adjacent slits. A helium-neon laser with wavelength λ=632.8 ×10^-9 m is emitting a narrow band of light, given by -10^-6<θ<10^-6, through a grating with 10,000 slits spaced 10^-4 m apart. Use the Midpoint Rule with n=10 to estimate the total light intensity ∫-10^-6^10^-6 I(θ) d θemerging from the grati$

$SOLVED:∙When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ±17.8^∘ from the central maximum. (a) What is the line density (in lines/cm) of this grating? (b) How many additional bright spots are there beyond the first bright spots, and at what angles do they occur?$

$SOLVED: Monochromatic light of wavelength 500 nm is incident normally on a diffraction grating. The third-order maximum of the diffraction pattern is observed at 32 degrees from the central spot.a. What is the angle of the first-order maximum?(I do not know how to solve for part a)b. How many total numbers of maxima can be seen?(I believe for part b it is 11 maxima because you can use "d sin (theta) = m (lambda)" and use that "d" to plug into "n = d/lambda," but I am not 100% sure)$
