A thin mica sheet of thickness 
m and refractive index ( μ μ = 1.5) is introduced in the path of the first wave. The wavelength of the wave used is 5000Å. The central bright maximum will shift
Text Solution
Verified by ExpertsThe correct answer is:
A
By using shift 
⇒ ⇒ 
Since the sheet is placed in the path of the first wave, so shift will be 2 fringes upward.
