ooo AT&T; LTE 8:15 PM webassign.net 52% An insect 3.80 mm tall is placed 22.2 cm to the left of a thin planoconvex lens. The left surface of this lens is flat, the right surface has a radius of curvature of magnitude 13.4 cm, and the index of refraction of the lens material is 1.55 (a) Calculate the location of the image this lens forms of the insect. Calculate the size of the image. Is it real or virtual? real virtual Erect or inverted? erect O inverted (b) Repeat part (a) if the lens is reversed. Calculate the location of the image this lens forms of the insect. location Calculate the size of the image. Is it real or virtual? o real virtual Erect or inverted? o erect O inverted (a) Where is the near point of an eye for which a contact lens with a powerExplanation / Answer
a) 1/f = (n-1) [1/R1 - 1/R2] = (1.55 - 1) [1/infinity - 1/-13.4] = 24.36 cm
1/f = 1/di + 1/do
1/di = 1/24.36 - 1/22.2
di = -2.5 m = -250 cm
m = -di/do = hi/ho
hi = 250 / 22.2 * 3.80 * 10-3= 42.79 mm
virtual and erect
b) a) 1/f = (n-1) [1/R1 - 1/R2] = (1.55 - 1) [1/13.4 - 1/infinity = 24.36 cm
1/f = 1/di + 1/do
1/di = 1/24.36 - 1/22.2
di = -2.5 m = -250 cm
m = -di/do = hi/ho
hi = 250 / 22.2 * 3.80 * 10-3= 42.79 mm
