(adsbygoogle = window.adsbygoogle || []).push({}); 1. using differentiation,find the angular separation in arc minutes in second order for two wavelengths 589.0 and 589.6 nanometers

2. d sin([tex]\theta[/tex])=m ([tex]\lambda[/tex])

3. i try to use D=[tex]\delta[/tex][tex]\theta[/tex]/[tex]\delta[/tex][tex]\lambda[/tex]

by differentating d sin([tex]\theta[/tex])=m ([tex]\lambda[/tex]) i got d/m sec(thetha).this equation can be further change to D=(sinA+sinB)/[tex]\lambda[/tex]sinB.

i assumed D is the separation between the wavelengths.is it the correct way to approach the problem??
