Problem 1. A concave-convex lens with index of refraction n = 3/2, radii of curvature R1 = ?3cm and R2 = 1cm is 4cm to the left of a diverging lens having focal length ?2cm. An object is placed to the left of both lenses at a distance 7 cm from the concave-convex lens. (a) Where is the final image formed by this combination of lenses? (b) Is the final image upright or inverted? (c) Is the final image real...
A typical human lens has an index of refraction of 1.430. The lens has a double convex shape, but its curvature can be varied by the ciliary muscles acting around its rim. At minimum power, the radius of the front of the lens is 10.0 mm, whereas that of the back is 6.00 mm. At maximum power, the radii are 6.50mm and 5.5mm, respectively. If the lens were in air: What would be the maximum power and associated focal length...
The figure below shows a thin converging lens for which the radii are R1 = 9.70 cm and R2 = -10.7 cm. The lens is in front of a concave spherical mirror of radius R = 7.32 cm. If its focal points F1 and F2 are 4.96 cm from the vertex of the lens: a) Determine its index of refraction. b) If the lens and mirror are 21.3 cm apart and an object is placed 8.63 cm to the left...
