Final answer:
A lower power lens, such as the 4X lens, requires less light.
Step-by-step explanation:
When a lower power lens, such as the 4X lens, is in place, you will need less light. This is because lower power lenses have a smaller magnifying power and allow more light to pass through. The smaller magnification means that the lens does not gather as much light, so less light is needed to create a clear image.
