Sodium’s emission lines at 589.0 nm and 589.6 nm pass through a diffraction grating and form two m = +1 maxima on a viewing screen. For which situation would the spacing between the two lines increase?
The intensity of the light is doubled.
The grating is exchanged for one with twice the total number of lines.
The maxima are viewed in second order.
The grating is exchanged for one having fewer lines per millimeter
Homework Answers
As we know angular seperation between the two maxima created by the two wavelengths is proportional to the order of maxima. It is expressed by the formula
Angular seperation ,
Where m is oder of maxima, d is seperation between the grating
lines, and 
is angular position of maxima, 
if difference between the wavelength.

The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a.

The spectrum of sodium has two closely spaced lines, known as the sodium doublet, with wavelengths 589.0 nm and 589.6 nm. When sodium light is incident on a diffraction grating with 4,300 rulings/cm, the maxima corresponding to this doublet are separated by Δy = 4.80 mm when the screen is L = 1.70 m from the grating. What is the value of m in this situation?
