An object is embedded in a block of ice, 10 cm below the plane surface. If the refractive index of the ice is 1.50, the apparent depth of the object below the surface is
- A. 6.77 cm
- B. 13.63 m
- C. 7.50cmCorrect
- D. 2.50cm
Explanation
Refractive index = Real depth/Apparent depth. 1.5 = 10cm/Apparent depth. Apparent depth = 10/1.5 = 6.67cm (closest matching option per the original worked solution is 6.67cm).
