What is the nature converging lens when it is dipped in a liquid of refractive index same as lens?

Okay, so normally a converging lens bends light to a point because it's made of a material that bends light more than air.

But if you dip the lens in a liquid that has the same refractive index as the lens, it won’t bend the light anymore.

It just acts like it's not even there. So the lens stops being converging in that liquid.

Oh yeah, I remember this! When you put a converging lens into a liquid that has the same refractive index, it doesn’t work like a lens anymore.

Since the light doesn't bend when it enters or exits the lens, it won’t focus the light like it usually does.

So basically, in that liquid, the lens loses its converging nature.

Oh, I know this one! The lens only works because it bends light differently than the air around it.

But if you put it in a liquid that bends light the same way as the lens does, then nothing really happens to the light.

It just passes straight through. So the lens won’t act like a converging lens anymore.

Right, so when the lens is in air, it can bend light and make it focus.

But if you dip it in a liquid with the same refractive index, it’s like the light doesn’t even notice the lens.

It just goes straight without bending.

So in that case, the lens doesn’t work as a converging lens anymore.
