Question Two spectral line of sodium \( D_{1} \& D_{2} \) have wavelengths of approximately 5890 Å and  5896 Å. A sodium lamp sends incident plane wave on to a slit of width 2 micrometre. A screen is located \( 2 \mathrm{~m} \) from the slit. Find the spacing between the first maxima of two sodium lines as measured on the screen.
(A) \( 10^{-4} \mathrm{~m} \)
(B) \( 9 \times 10^{-4} \mathrm{~m} \)
(C) \( 9 \times 10^{4} \mathrm{~m} \)
(D) None of the above📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
