A concave mirror has a radius of curvature R and forms the image of an object placed at a distance 1.5 R from the pole of the mirror. An opaque disc of diameter half the aperture of the mirror is placed with the pole at the centre. As a result

Options

  1. Athe position of the image will be the same but its central half will disappear
  2. Bthe position of the image will be the same but its outer half will disappear
  3. Cthe complete image will be seen at the same position and it will be exactly identical with the initial image
  4. Dthe complete image will be seen at the same position but it will not be identical in all respect with the init

Correct answer

D. the complete image will be seen at the same position but it will not be identical in all respect with the init
