An object is placed directly below a glass block of thickness 3.0cm. Calculate the lateral displacement of the object if the refractive index of the glass is 1.5.
-
1.0cm
- 1.5cm
- 2.0cm
- 2.5cm
The correct answer is: A
Explanation
1.5 = \(\frac{3}{\text {apparent displacement}}\)Apparent depth = 2cm
displacement = 3 - 2
= 1cm
