At a distance of 6 meters, a person with average vision is able to clearly read letters 1.0 cm high.

Approximately how large do the letters appear on the retina? (Assume that the retina is 1.7 cm from the lens.)

Magnification is the process of visually enlarging an object, not physically increasing its size but only increasing its apparent size.The ratio of the image's height to the object's height is represented by the formula for magnification. Additionally, the letter "m" stands for the object's magnification. Additionally, its formula is Magnification (m) is equal to h/h'. Here, the object's height is represented by h and its height by h'.

How to calculate and form equations?

It is given in the question that,

Object separation, u = 6 meters

Lens distance from retina is v = 1.7 cm = 0.017 m.

Height of the object: hu = 1.0 m

here, magnification = [tex]-\frac{v}{u}[/tex] = [tex]\frac{hv}{hu}[/tex]

now, -[tex]\frac{o.o17}{6}[/tex] = [tex]\frac{hv}{1}[/tex]

[tex]hv = \frac{-0.017}{6}[/tex]

[tex]hv = -0.002833m[/tex]
