Hi everyone,
I've got this assignment for astronomy class to do:

Basically I'm having a bit of trouble for the part in the image that I highlighted. I can't seem to figure out $$\lambda$$. I know what the behavior of the system is supposed to look like for different cases of $$\lambda$$, I just can't seem to come up with it. Any help would be great!
