Formation of real image using a biconvex lens is shown below: If the whole set up is immersed in water without disturbing the object and the screen positions, what will one observe on the screen?

Options

  1. AImage disappears
  2. BMagnified image
  3. CErect real image
  4. DNo change

Correct answer

A. Image disappears

Step-by-step solution

When we put our system in water, the focal length of lens is increased. Now image is not formed on screen.
