Answer:
3.28 degree
Explanation:
We are given that
Distance between the ruled lines on a diffraction grating, d=1900nm=
Where 
We have to find the angular width of the gap between the first order spectrum and the second order spectrum.
We know that
Using the formula
m=1
Now, m=2
Hence, the angular width of the gap between the first order spectrum and the second order spectrum=3.28 degree
