A concave lens of refractive index 1.5 is immersed in a medium of refractive index 1.65. What is the nature of the lens ? Concave lens is immersed in medium having refractive index greater than the refractive index of the material of the lens therefore it will be have such converging lens .

vatsalagarwal123: Since refractive index of lens is less than refractive index of surroundings, it will behave as a convex lens. in short

beccajoy1109: I wanted to know if we can write it this way as well... Since the refractive index of the medium is greater than the lens, the nature of the lens will change. this is due to the relation... 1/f=(d-1) where d is the relative refractive index of the 2 media. This also implies that the nature of the lens will not change if the RI of the lens is greater than that of the medium.

the lens is disappeared and the both refractive index getting same
