Question

Match the items given in column I with one or more items of column II. [4 marks]

Answer 1

The first item in column I is (A) a plane mirror. Match it with (v). As the image formed by a plane mirror is erect and of the same size as the object. [0.5 marks]
The second item in column I is (B) a convex mirror. A convex mirror is also known as a diverging mirror. It diverges the light rays that strike on it. That’s why it can form images of objects spread over a large area. Also, the image formed by a convex mirror is erect and smaller in size than the object. So, match it with (ii) and (vi). [1 mark]
The third item in column I is (C) a convex lens. A magnifying glass is a convex lens used to make an object appear much larger than it actually is. So, match it with (i). [0.5 marks]
The fourth item in column I is (D) a concave mirror. Dentists use concave mirrors to see teeth and other areas in the mouth. This is because a concave mirror forms a virtual, erect and enlarged image when the object is placed very near.[1 mark]
The fifth item in column I is (E) a concave lens. A concave lens is diverging in nature. . It diverges the light rays that strike on it. That’s why it can form images of objects spread over a large area. Also, the image formed by a concave lens is erect and smaller in size than the object. So, match it with (ii) and (vi). [0.5 marks]
One of the items in column II is left i.e. ‘The image is always inverted and magnified”. It is not possible to ALWAYS form an inverted and magnified image with mirrors and lenses. [0.5 marks]
