Answer:

the beetle's actual distance beneath the surface, d = 3.2 cm

Explanation:

The refractive index for the plastic is about 1.60

For overhead viewing, the expression for refractive index is

n = actual depth / apparent depth

Rearrange for actual depth

actual depth d = n x apparent depth

d = 1.60 x 2.0 cm

d = 3.2 cm
