CUET Preparation Today
Two transparent sheets of equal thickness and same refractive index are placed in front of both the slits of YDSE. Now the two sheets are interchanged. The fringe width will |

$β=\frac{λD}{d}$ As none of $λ$, D and d changes due interference of transparent sheets, hence $β$ remains constant. |
