One face of a rectangular glass plate 6 cm thick is silvered. An object held 8 cm in front of the first face, forms an image 12 cm behind the silvered face. The refractive index of the glass is
Text Solution
Verified by ExpertsThe correct answer is:
C
Let x be the apparent position of the silvered surface.
According to property of plane mirror
x + 8 = 12 + 6 – x 
x = 5 cm
