(d) A convex mirror always gives a virtual and erect image of smaller size of the object placed in front of it. Similarly, a plane mirror will always give a virtual and erect image of same size as that of the object placed in front of it. Therefore, the given mirror could be either plane or convex.Read more

(a) both concave By convention, the focal length of a concave mirror and a concave lens are taken as negative. Hence, both the spherical mirror and the thin spherical lens are concave in nature.

(a) both concave
By convention, the focal length of a concave mirror and a concave lens are taken as
negative. Hence, both the spherical mirror and the thin spherical lens are concave in
nature.
(b) When an object is placed at the centre of curvature in front of a convex lens, its image is formed at the centre of curvature on the other side of the lens. The image formed is real, inverted, and of the same size as the object. For more answers visit to website: https://www.tiwariacademy.com/ncRead more
(b) When an object is placed at the centre of curvature in front of a convex lens, its image
is formed at the centre of curvature on the other side of the lens. The image formed is
real, inverted, and of the same size as the object.
(d) When an object is placed between the pole and principal focus of a concave mirror, the image formed is virtual, erect, and larger than the object. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-10/science/chapter-10/
(d) When an object is placed between the pole and principal focus of a concave mirror,
the image formed is virtual, erect, and larger than the object.
(d) A lens allows light to pass through it. Since clay does not show such property, it cannot be used to make a lens. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-10/science/chapter-10/
