Thank you for the opportunity to help you with your question!

the dark fringes equation in single slit is

a sintheta = m lambda m = 1 ,2 ,3... 

m = 2 in this case 

sintheta = 2 *6 x10^-7 / 4x10^-4 

s = 2theta = 4 *6 x10^-7 / 4x10^-4   

=6x10^-3 m

Please let me know if you need any clarification. I'm always happy to answer your questions.
