Question

A diffraction grating 17.0 mm wide has7020. rulings.

(a) Calculate the distance d between adjacentrulings.
1 mm
(b)At what angle will the second intensity maximum occur if theincident radiation has a wavelength of 560. nm?
2°

A diffraction grating has a slit separation of 2 x10-6 m. Calculate the wavelength of the monochromaticlight that will have its second order bright fringe diffractedthrough an angle of 38.0º. my answer is 6.157e-7 meters. I just want to make sure myanswer is correct. Thanks!

Explanation / Answer

Width W = 17 mm

No.of ruling N = 7020

So, distance between adjacent ruling d = W / N = 2.421 * 10^ -3 mm
