Problem 2: Two lenses Consider two converging lenses: first with the focal length f₁ = 3m, second with f₂ = 2m which are 50 cm apart. We place the object with height 2 cm at a distance 4m to the left from the first lens. a) What is the distance of the image from the first lens? Is it on the right/left from the first lens? Is the image real/virtual? b) What is the height of the image and total magnification of the system? Is the image upright or inverted? c) What is the focal length of the system, ie. the distance from the second lens where the parallel rays coming from the left intersect the optical axis?

Transcribed Image Text:Problem 2: Two lenses
Consider two converging lenses: first with the focal length f₁ = 3m, second with f₂ = 2m which are
50 cm apart. We place the object with height 2 cm at a distance 4m to the left from the first lens.
a) What is the distance of the image from the first lens? Is it on the right/left from the first lens? Is
the image real/virtual?
b) What is the height of the image and total magnification of the system? Is the image upright or
inverted?
c) What is the focal length of the system, ie. the distance from the second lens where the parallel rays
coming from the left intersect the optical axis?
