In a Young's double slit experiment, a monochromatic light of wavelength \(600 \mathrm{~nm}\) is used. If the two slits are covered by transparent sheets of thickness \(0.132 \mathrm{~mm}\) and \(0.1 \mathrm{~mm}\) of refractive index 1.5 , then the number of fringes that will shift due to introduction of the sheets are
- A 27
- B 40
- C 60
- D 80
Answer & Solution
Correct Answer
(A) 27
Step-by-step Solution
Detailed explanation
(No option is matching) Number of fringes shift due to extra path difference caused by transparent slab is \[ n=\frac{(\mu-1) t}{\lambda} \] So, when two plates of thickness \(t_1\) and \(t_2\) are placed infront of slits, then shift is…
