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.
1 answer:
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
