#### A postage stamp kept below a rectangular glass block of refractive index 1.5 when viewed from vertically above it , appears to be raised by 7.0 mm. Calculate the thickness of the glass block.



Refractive index = real / apparent depth Let real depth be ( x ) therefore apparent depth will be ( x - 7mm) given refractive index is 1.5 therefore >1.5 = x/ (x-7mm) >1.5x - 10.5 =x. ie 1.5(x - 7mm) &#...
