Match List-I with List-II regarding the ratio of apparent depth (or height) to real depth (or height) for different combinations of observer and object media. Assume near normal viewing. The refractive indices are: Air ( n=1 ), Water ( n=4/3 ), and Glass ( n=3/2 ). List-I List-II A. Observer in Air, Object in Water 1. 4/3 B. Observer in Water, Object in Air 2. 3/4 C. Observer in Glass, Object in Water 3. 8/9 D. Obser

Step-by-step solution

The ratio of apparent depth (or height) to real depth (or height) is given by the formula: h_ app h_ real = n_ observer n_ object For A: Observer in Air ( n=1 ), Object in Water ( n=4/3 ). Ratio = 1 4/3 = 3 4 . So, A matches with 2. For B: Observer in Water ( n=4/3 ), Object in Air ( n=1 ). Ratio = 4/3 1 = 4 3 . So, B matches with 1. For C: Observer in Glass ( n=3/2 ), Object in Water ( n=4/3 ). Ratio = 3/2 4/3 = 9 8 . So, C matches with 4. For D: Observer in Water ( n=4/3 ), Object in Glass ( n=3/2 ). Ratio = 4/3
