Diffraction of light and orders equation??
A particular grating has slits of width 600nm and a slit separation of 1800nm. Will there be any missing orders if this is used to observe a line spectrum consisting of 450nm, 600nm and 650nm?
I'm not sure what formula to use but think it may be either
n=d sin theta/lamda or
a sin theta/n lamda
As I'm not sure even what equation to use I'm not going to attemp it. Can someone just tell me what equation I need in order to answer the question. I'm sure I could figure it out if I just know what the equation is.
Thanks
