Answer Key / Explanation : (b) -
|
(b) For possible interference maxima on the screen, the condition is
Given :
The maximum value of Thus, Eq. (i) must be satisfied by 5 integer values ie, -2 -1, 0, 1, 2. Hence, the maximum number of possible interference maxima is 5. |
…(i)
slit-width 
is 1, hence,
