An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...

1) A single bi-convex lens (a lens with two convex surfaces) made of fused quartz (index of refraction n = 1.46) has surfaces with radii of curvature r1 = 17.0 cm and r2 = -17.0 cm. What is the focal length of the lens in air? Tries 0/12 2) If an object is placed at p = 36.4 cm from the lens, where is the image? (Use plus sign for a real image, and minus sign for a virtual image.)...

The figure below shows a thin converging lens for which the
radii are R1 = 9.32 cm and R2 = -11.4 cm. The lens is in front of a
concave spherical mirror of radius R = 7.92 cm. If its focal points
F1 and F2 are 4.60 cm from the vertex of the lens: a)
Determine its index of refraction.
b) If the lens and mirror are 19.7 cm apart and an object is placed
8.21 cm to the left...

SOLUTION SET UP The center of curvature of the first surface of the lens is on the outgoing side, so R = +6.0 mm. The center of curvature for the second surface is not on the outgoing side, so R2-_5.5 mn. We solve for f and then use the result in the thin-lens equation. Now we'll apply the thin-lens equation to the eye When light enters your eye, most of the focusing happens at the interface between the air and...
