Do i have to answer the question and still have the offer on the table
Answer:
n = 3
Solution:
Since, the slit used is same and hence slit distance 'x' will also be same.
Also, the wavelengths coincide, will also be same.
Using Bragg's eqn for both the wavelengths:
(1)
(2)
equate eqn (1) and (2):
n = 3
