Question

monochromatic light of wavelength 500 nm is used in young's double slit experiment . one of the slit is covered by a glass sheet of thickness 2.0×10^_2mm and refractive index 1.5. the no. of fringes shifted by the introduction of the sheet is​

Answer 1

Answer:

We have, (μ−1)t=nλ where n is the no. of fringes that shifted.
