Answer:

2/3 cm

Explanation:

Given that:

Refractive index = 1.5

Real depth =?

Apparent depth = 2 m

Using the relation :

Refractive index = Real. Depth / Apparent depth

1.5 = Real depth / 2

Real depth = 2 * 1.5

Real depth = 3 cm

How much the picture appear raised :

Apparent depth / Real depth

= 2 /3 cm
