Question

The focal point of a lens depends on which two things?A.The center of curvature for the two sides of the lensB.The properties of the material it is made fromC.The material the object is made fromD.The location of the object

Answer 1

We are asked to determine on which properties the focal length depends.

The focal lens is a function of the refractive index which in turn is a property of the material the lens is made of, therefore, the focal lens depends on the properties of the material the lens is made of.

The focal length also depends on the curvature of both surfaces of the lens.

therefore, the right answers are A and B.
