In Young's double slit experiment, the ratio of amplitude of light coming from two slits is \( 2: 3 \). If \( I _{0} \) be the maximum intensity the resultant intensity I when they interfere at path difference \( \lambda / 3 \quad(\lambda= \) wavelength of light) will be (1) \( \frac{3 I_{0}}{25} \) (2) \( \frac{6 I_{0}}{25} \) (3) \( \frac{7 I_{0}}{25} \) (4) \( \frac{9 I_{0}}{25} \)
