Consider the following statements regarding the apparent depth of an object placed in a denser medium: 1. An observer looking vertically down into a swimming pool perceives it to be shallower than it actually is. 2. The apparent shift in the position of an object increases if the refractive index of the medium increases. 3. The apparent shift is completely independent of the wavelength of light used to illuminate the object. Which of the statements given above are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1 and 3 only
• D: 1, 2 and 3
