A) infinite
B) five
C) three
D) zero
Correct Answer: B
Solution :
For possible interference maxima on the screen, the condition is \[{{40}^{o}}C\] Given, \[{{80}^{o}}C\] \[{{100}^{o}}C\] \[{{20}^{o}}C\] ?..(i) The maximum value of sin 9 is 1, hence \[R=8.31Jmo{{l}^{-1}}{{K}^{-1}}\] Thus, Eq. (i) must be satisfied by 5 integer values i.e., \[996\text{ }J\]You need to login to perform this action.
