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]) = I0 [sin([tex]\Pi\alpha[/tex])/[tex]\Pi\alpha[/tex]]2 where I0 is the intensity at the central peak 3. The attempt at a solution I have no idea how to begin..
