Solution

Explanation:
A convex lens of a focal length of 20 cm can produce a magnified virtual as well as a real image. This statement is correct
If we want to produce a real image with this convex lens, we need to place the object between the center of curvature and the principal focus
This can be illustrated using a diagram
A virtual image can be produced using this convex lens by placing the object between the principal focus and the pole

In the diagrams above,
F= Principal focus
C=Center of curvature
AB=Object
A'B'=Image
Arrows =Direction of rays

Type 0 or 1 as your answer

A concave mirror of a focal length of $10 c m$ can produce a magnified real as well as a virtual image of an object placed in front of it. Draw ray diagrams to justify this statement.
