Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The given formula is for structure factor When you put value of hkl (1+0+(-1))=0 the resultant answer is e^(0) =1 so option a 1 is the correct option
e^0 kyu lenge sir??
when you put h k l valor as +1 0 and - 1 then the answer is zero and zero multiple of anything is zero so the raise to whole term becomes zero. hence e^(0) which is equal to 1. hope this helps
ok sir thanku
