Step 1
Total Power of the Combined Lenses
Answer
To find the total power of two thin converging lenses positioned next to each other, we simply add their individual powers.
Given that each lens has a power of 4D, we calculate the total power as follows:
Thus, the total power of the combined lenses is 8D.
