What is the beetle’s actual distance beneath the surface?

Posted by

A biologist keeps a specimen of his favorite beetle embedded in a cube of polystyrene plastic. The hapless bug appears to be 2.0 cm within the plastic.

d_actual = ? cm

    You forgot to give the refractive index for the plastic .. assuming it is 1.60

    For overhead viewing .. n = actual depth / apparent depth

    actual depth d = n x app. depth = 1.60 x 2.0cm .. .. .. ►d = 3.20 cm
