A fish at a depth of 12 cm in water is viewed by an observer on the bank of a lake. To what height the image of the fish is raised? (Refractive index of lake water = 4 3 )

Options

  1. A9 cm
  2. B12 cm
  3. C3.8 cm
  4. D3 cm

Correct answer

D. 3 cm

Step-by-step solution

Apparent rise =d (1- 1 a _w ) aligned & =12 (1- 3 4 ) & =12 1 4 =3 ~cm aligned
