(3%) Problem 14: The print in many books averages 3.50 mm in height. Randomized Variables do - 25 cnm How big (in mm) is the image of the print on the retina when the book is held 25 cm from the eye? Assume the distance from the lens to the retina is 2.00 cm Grade Summary Deductions Potential 0% 100% sin( cos0 tanOt ( acos) Submissions Attempts remaining: 2 % per attempt) detailed view atan)acotan)sinhO coshO tanhO cotanhO Degrees O Radians 0 END Submit Hint I give up!

How do you define magnification, relative to both the object-image distances and the object-image sizes?

Explanation / Answer

hi/ho = -(di/do)

here di = 2cm

do = 25 cm

ho = 3.5 mm

hi = ??

hi = -ho(di/do)

hi = -3.5mm * ( 2/25)

hi = -0.28 mm
