A single by bi-convex lens made of glass (index of refraction n=1.50 ) has surfaces with the radii of curvature R1= 26.0 cm and R2= -26 cm. (a) What is this focal length of the lens in the air? (b) if an object is placed at p=32 cm from the lens, where is the image? (Use plus sign for a real image, minus signs for the virtual.) (c) if the subject has a height of h+1.50 cm, how large is the image? (Use plus sign for an upright image and minus sign for an inverted image.)

The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.46. We shall assume that the radii of curvature of its two surfaces have the same magnitude. Assume the lens is embedded in a fluid having refractive index similar to air. If the radii of curvature of this lens is 7.82mm, what is its focal length? If an object 10.0 mm tall is placed 17.0 mm from the eye lens,...

1) Two convex lenses, both with focal length 1.5 m, are placed such that the light from a 4 cm tall object passes through each. The object is placed 4.5 m from the first lens, and the lenses are 3 m apart. Where will the image from the first lens be? Will it be real or virtual? Will it be upright or inverted? Where will the final image be (using both lenses)? Will it be real or virtual? Upright or...

A thin lens is made of glass that has refractive index n = 1.50. The lens is surrounded by air. The left-hand spherical surface of the lens is concave with radius of curvature R and the right-hand side is flat, so the lens is thinner in the middle than at its edges. An object is placed 12.0 cm to the left of the center of the lens. What is the value of R if the image formed by the lens...
