A diffraction grating has a length of 1.1 cm and contains 1.7e4 lines. Calculate the first order diffraction angle for light with a wavelength of 448 nm. Give you answer in degrees. Anyone know??

That's n*lambda = d*sin theta.
n = 1
lambda is given
d = distance between lines. Wouldn't that be 1.1 cm/1.7e4 = ?
Make sure cm and nm are in same units.
