In Young's double slit experiment, the \( y \) coordinates of central maxima and \( 10^{th} \) maxima are at \( 2\ \text{cm} \) and \( 5\ \text{cm} \) respectively. When the apparatus is immersed in a liquid of refractive index \( 1.5 \), the corresponding \( y- \)coordinates will be:
1
\( 2\ \text{cm},\ 4\ \text{cm} \)
2
\( \dfrac{4}{3}\ \text{cm},\ \dfrac{10}{3}\ \text{cm} \)
3
\( 2\ \text{cm},\ 7.5\ \text{cm} \)
4
\( 3\ \text{cm},\ 6\ \text{cm} \)
5
