What changes in focal length when a mirror is dip into water??

1.	What changes in focal length when a mirror is dip into water??
Answer» Hii mate The focal length of a LENS is very MUCH affected when immersed in water. The reason is that the angle of refraction is dependent on the RELATIVE DIFFERENCE between the indices of refraction of the incoming medium and the medium of the lens. ... Your eyes' focal length change dramatically thanks
