The displacement d produced in a glass block of thickness t and refractive index n when an object is viewed through it is
Answer Details
When light passes through a medium with a different refractive index, it changes its direction. This effect is known as refraction. The amount of bending that occurs depends on the angle of incidence and the refractive indices of the two media involved.
In this case, we are looking at the displacement produced in a glass block of thickness t and refractive index n when an object is viewed through it. The amount of displacement (d) can be calculated using the formula:
d = t (1 - 1/n)
Where t is the thickness of the glass block and n is the refractive index of the glass.
Therefore, the correct option is (C), which gives the displacement as t (1 - 1/n).
