37.0 cm to the left of the vertex
of the spherical surface. The image is formed in the rod, 50.0 cm
to the right of the vertex.
(a) What is the magnitude of the radius of curvature of the
spherical surface at the end of the...

The left end of a long glass rod 5.82 cm in diameter has a
convex hemispherical surface 2.91 cm in radius.The refractive index
of the glass is 1.60. The rod is immersed in a liquid. An object
88.8 cm from the vertex of the left end of the rod and on its axis
is imaged at a point 1.64 m inside the rod.
What is the refractive index of the liquid?

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
