 MCAT Question of the Day
 0.5 diopters
 10 diopters
 25 diopters
 50 diopters
Click for Explanation
The question stem states that image distance is fixed and equal to a length of 2 cm. Since the question states that the observer stares at a distant object, we can assume that 1/d_{o }is negligible and equal to zero. Therefore, the equation simplifies to P = 1/d_{i}. Since power is measured in diopters, which has the units of m^{1}, you must convert 2 cm to 0.02 m and solve. Thus, the power of the lens is equal to 50 diopters, or answer choice D.
