# If spherical mirrors and lenses are placed in different mediums like water etc , then will the focal length of the spherical mirror or lens change??

Dear student
The focal length of the mirror will not change because it does not depend upon the nature of the medium in which it is placed but the focal length of the lens will change since it depends upon the nature of the medium in which it is placed.
Hope this helps.
