Question

Find out the missing order for a double-slit Fraunhofer Diffraction
pattern if the slit widths are 0.2 mm separated by 0.6 mm.
2. What is the highest order spectrum, which may be seen with
monochromatic light of wavelength 600 nm by means of diffraction
grating with 5000 lines per cm?
3. Light of wavelength (λ) = 500 nm falls on a grating normally. Two
adjacent principal maxima occur at sinθ = 0.2 and sinθ = 0.3
respectively. Calculate the grating element.
4. How many orders would be visible, if the wavelength of incident
light is 589 nm and the number of lines in the grating is 100 per mm?
