diameter of her pupil is 6.54 mm and the diameter of her eye is 1.94 cm?
W/m²
Required information
An object is placed 20.0 cm from a converging lens with focal length 15.0 cm (see the figure, not drawn to scale). A
concave mirror with focal length 10.0 cm is located 76.5 cm to the right of the lens. Light goes through the lens, reflects
from the mirror, and passes through the lens again, forming a final image.

Required information
A man requires reading glasses with +2.15-D refractive power to read a book held 40.0 cm away with a relaxed eye.
Assume the glasses are 1.90 cm from his eyes.
His uncorrected near point is 1.00 m. If one of the lenses is the one for distance vision, what should the refractive power of the other
lens (for close-up vision) in his bifocals be to give him clear vision from 25.0 cm to infinity?
