Explanation:

A convex lens generally acts as a converging lens when placed in a medium of refractive index less than that of the lens and acts as a diverging lens when placed in a medium of refractive index greater than that of the lens.

i hope it will helps you ❣️,,, sorry I didn't get the diagram
