Assertion: In YDSE, if I 1=9 I 0 and I 2=4 I 0 then ( I max / I min )=25. Reason: In YDSE I max =(1/2)(√I1+√I2)2 and I min =(1/2)(√ I 1-√ I 2)2.

Correct answer is (c) If the Assertion is correct but Reason is incorrect.

Q. Assertion : In YDSE, if I1​=9I0​ and I2​=4I0​ then Imin​Imax​​=25. Reason : In YDSE Imax​=21​(I1​​+I2​​)2 and Imin​=21​(I1​​−I2​​)2.

Ifboth Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Q. Assertion : In YDSE, if $I_{1} = 9 I_{0}$ and $I_{2} = 4 I_{0}$ then $\frac{I _{m a x}}{I _{m i n}} = 25$ .
Reason : In YDSE $I_{m a x} = \frac{1}{2} (I_{1} + I_{2})^{2}$ and $I_{m i n} = \frac{1}{2} (I_{1} - I_{2})^{2}$ .
