A coin placed below a rectangular glass prism of thickness 7.5cm and refractive index 1.5 is viewed vertically above the glass. Calculate the apparent displacement of the coin.

Respuesta :

Answer:

The apparent displacement of the coin is 2.5 cm

Step-by-step explanation:

Mathematically;

shift = real depth * (1-1/refractive index)

From the question;

real depth = 7.5 cm and refractive index = 1.5

Thus, substituting this, we have;

shift = 7.5 * (1-1/1.5)

shift = 7.5 * (1/3)

shift = 7.5/3 = 2.5 cm
