Figure 21.1 The figure shows the real and apparent positions of a fish in water. -We are looking at a fish from directly above (Fig. 21.1). If the fish looks to us to be 30 cm beneath the surface, where is its real position as measured from the surface? Indices of refraction are, for air n₁ and water n₂, n₁ = 1 and n₂= 1.33.

The Answer of Figure 21.1 The figure shows the real and apparent positions of a fish in water. -We are looking at a fish from directly above (Fig. 21.1). If the fish looks to us to be 30 cm beneath the surface, where is its real position as measured from the surface? Indices of refraction are, for air n₁ and water n₂, n₁ = 1 and n₂= 1.33.
