I could you please see why my answer is only partial correct.

Thanks!

A spherical surface of radius +7 cm is polished on the end of a glass rod of refractive index 1.55. Note: write your answer in 3 decimal places. gure 1. This illustration shows the glass rod placed in air. gure 2. This illustration shows the glass rod placed in water. gure 3. This illustration shows the glass rod placed in the oil. gure 4. This illustration shows the glass rod placed in liquid. Part {1}. Find its power when placed in air Your last answer was interpreted as follows: 11.000 Part {2}. Find its power when placed in water of refractive index 1.333 4.340 Your last answer was interpreted as follows: 4.340 Part {3).
