which shows the correct lens equation?\no 1/f = 1/di × 1/do\no 1/f = do/di + di/do\no 1/f = 1/do - 1/di\no 1/f = 1/do + 1/di
Answer
Explanation:
Step1: Recall lens - formula concept
The lens formula relates the focal length ($f$), object - distance ($d_o$), and image - distance ($d_i$) for a thin lens.
Step2: State the correct formula
The correct lens formula is $\frac{1}{f}=\frac{1}{d_o}+\frac{1}{d_i}$.
Answer:
$\frac{1}{f}=\frac{1}{d_o}+\frac{1}{d_i}$ (the fourth option)
