A monochromatic beam of light falls on YDSE apparatus at some angle (say θ) as shown in figure. A thin sheet of glass is inserted in front of the lower slit S2 . The central bright fringe (path difference = 0) will be obtained
- At O
- Above O
- Below O
- Anywhere depending on angle \(\theta\), thickness of plate t and refractive index of glass \(\mu\)
