PART I::PHYSICS
Section 1 (maximum marks: 32)
• This section contains EIGHT (08) questions.
• Each question has FOUR options ONE OR MORE THAN ONE of these four option(s) is(are) correct answer(s).
• For each question, choose the option(s) corresponding to (all) the correct answer(s).
• Answer to each question will be evaluated according to the following marking scheme. Full Marks +4 If only (all) the correct option(s) is (are) chosen;
Partial Marks +3 If all the four options are correct but ONLY three options are chosen;
Partial marks +2 if three or more options are correct but ONLY two options are chosen and both of which are correct;
Partial Marks +1 If two or more options are correct but ONLY one option is chosen and it is a correct option;
Zero Marks 0 If none of the options is chosen (i.e. the question is unanswered);
Negative Marks -1 In all other cases.
• For example, in a question, if
degree, there will be destructive interference at point O.
.
degree, there will be destructive interference at point P.
For 
= 0, there will be constructive interference at point P.
Text Solution
Verified by ExpertsC
Given 
degree = 
radian.
Path difference at O = d sin 
= 0.3 x 10 -3 x 
= 6 x 10 -7 = 
Path difference at P = d(sin 
+ sin 
)
For 
= 0, path difference at P = 5.5 
option C is correct
