Answer:
The focal length of a lens is depended on the surrounding medium. The reason behind this phenomenon is that the angle of refraction of a lens is depended on the indices of refraction of the medium of lens and the incoming medium and the difference in their indices

The material required to observe the factors on which the focal length depends are some board pins and measuring stand, lens of different material.
Explanation:
- The refractive index depends on the material of the lens . It also depends on the material which is present around the lens from start the curvature of the lens as a roll on the focal length
- if the curvature is increased then the focal length of the lens decreases.
- focal length plays a very important role in calculation of the position of the image in different orientation of the object
