Two thin lenses have powers P₁ and P₂,measured in diopters.If these lenses are placed in contact with one another,the resulting power is A)more than both P₁ and P₂. B)less than both P₁ and P₂. C)half-way between P₁ and P₂. D)P₁ + P₂.

Question

Quizplus · Accepted Answer

When two lenses are placed in contact with each other, the resulting power is equal to the sum of the individual powers. Therefore, the resulting power in this case is P₁ + P₂. Thus, the correct answer is D.
