A plastic hemisphere has a radius of curvature of 8 cm and a refractive index of 1.6. On the axis halfway between the plane surface and the spherical one (4 cm from each) is a small object O.The distance between the two images when viewed along the axis from the two sides of the hemisphere is approximately :

Answer» A plastic hemisphere has a radius of curvature of $8 cm$ and a refractive index of $1.6$ . On the axis halfway between the plane surface and the spherical one ( $4 cm$ from each) is a small object O. The distance between the two images when viewed along the axis from the two sides of the hemisphere is approximately :
