(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that the angular locations of the first to fourth secondary maximas are [tex]\alpha[/tex] = a sin [tex]\Theta[/tex]/[tex]\Lambda[/tex] = 1.43030 2.45902 3.47089 4.46641 respectively.

a is the slit width = 0.00016m

[tex]\Lambda[/tex] wavelength of laser 650nm

2. Relevant equations

I(_{[tex]\Theta[/tex]}) = I_{0}[sin([tex]\Pi\alpha[/tex])/[tex]\Pi\alpha[/tex]]^{2}

where I_{0}is the intensity at the central peak

3. The attempt at a solution

I have no idea how to begin..
