A myopic person has a near point of 28.0 cm and a far point of 43.0 cm. When correcting the distant vision with a lens, calculate the near point (in cm) of the corrected vision.

An object of height 5 mm is at the front focal point of a lens that has focal length of 50 mm, which is used as a simple magnifier. What is the angular subtense of the virtual image at infinity? Express in degrees. What is the approximate size of the retinal image, assuming a standard human eye? Express in mm

An object is placed a distance do = 19.0 cm in front of a positive (converging) lens of focal length f = 7.0 cm. = Where is the image formed relative to the lens position (positive to the right of the lens)? d₁ = What is the image magnification? m= cm Is the image upright or inverted? no image is formed inverted upright Is the image real or virtual? real O no image is formed virtual W do

A diverging lens has a focal length of magnitude 17.8 cm. (a) For an object distance of 44.5 cm, determine the following. What are the image distance and image location with respect to the lens? (Give the magnitude of the distance in cm.) image distance cm image location in front of the lens v Is the image real or virtual? virtual What is the magnification? Is the image upright or inverted? upright (b) For an object distance of p2 = 13.4 cm, determine the following. What are the image distance and image location with respect to the lens? (Give the magnitude of the distance in cm.) image distance cm image location in front of the lens v Is the image real or virtual? ---Select--- What is the magnification? Is the image upright or inverted? upright (c) For an object distance of p3 = 26.7 cm, determine the following. What are the image distance and image location with respect to the lens?

An object is placed a distance do = 6.0 cm in front of a positive (converging) lens of focal length f = 13.0 cm. Where is the image formed relative to the lens position (positive = to the right of the lens)? d₁ = What is the image magnification? m = cm Is the image upright or inverted? inverted upright no image is formed Is the image real or virtual? real O no image is formed O virtual o do

Thin lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in the table (below) gives object distance p (centimeters), the type of lens (C stands for converging and D for diverging), and then the distance (centimeters, without proper sign) between a focal point and the lens. Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual, (d) inverted from object O or noninverted, and (e) on the same side of the lens as object O or on the opposite side. р Lens +8.6 D, 22 (a) (b) (c) (d) (e) i m R/V I/NI Side

Calculate the power of the eye in D when viewing an object 4.18 m away. (Assume the lens-to-retina distance is 2.00 cm. Enter your answer to at least one decimal place.) D
