In Young's double slit experiment light of wavelength \(500 \mathrm{~nm}\) is used to form interference pattern. A uniform glass plate of refractive index 1.5 and thickness \(0.1 \mathrm{~mm}\) is introduced in the path of one of the interfering beams. The number of fringes that will shift due to this is
- A 400
- B 100
- C 300
- D 200
Answer & Solution
Correct Answer
(B) 100
Step-by-step Solution
Detailed explanation
The shift in the interference pattern in Young's double slit experiment when a glass plate of thickness \(t\) and refractive index \(\mu\) is introduced in the path of one of the beams is given by the formula: \(\Delta x = \dfrac{(\mu - 1)tD}{d}\) The number of fringes shifted…
