When Young's double slit experiment is performed in air, the
-coordinates of central maxima and
maxima are
and
respectively. If the apparatus is immersed in a liquid of refractive index 1.5, the corresponding Y-coordinates will be
Text Solution

For YDSE apparatus in air
For central maxima
………(i)
For
maxima

From equation (i), we have

Now, when the YDSE apparatus is immersed in a liquid of refractive index 1.5 , then it's wave length
As the y coordinate of central maximum doesn't depend upon wavelength, therefore it will remain same as in air,
For
maxima
